  1. If the kit is a universal fit and doesn't require an electronic speedo or HEI ignition, it should work fine.

    I did it many years back in a '66 Avanti I've long since sold, but unfortunately the Dana kit I used is long out of production. It used a magnet (attached to the driveshaft) and sensor, with a vacuum bellows in the engine compartment, a mechanical vacuum dump switch on the brake pedal linkage, a small electronic control box under the dash, and a replacement turn signal lever similar to those used by GM in that time period.

    It was not particularly hard to install, and worked fine. I do not recall if it had a "resume" or "accel" capability like modern cars, though, it may have only had an on/off switch and a speed set switch.

    Closest thing now is probably this Audiovox CCS-100 kit (and I doubt these are still in production): http://tinyurl.com/j3zer9r

    I wouldn't like that button control box, however... one can probably still find old 70's GM cars in junkyards that might have the column-mounted turn signal/cruise levers that could be adapted.

    Apparently some Dakota Digital setups use the same lever... I found this one on eBay:


    Google searches turned up the following:

  2. I haven't posted a photo here in several years, yet I don't recall the size limit being as low as 57kb; but, I was able to duplicate the method you used to post those thumbnail photos (see method 2, below).

    Method 1: I'll try simply plopping a photo into my reply right below here:


    Method 2: Here is what a photo loaded to the reply using the "More reply options", then "Browse", then "Attach This File" looks like (turns out to be just a thumbnail, as your post was, even though the photo is larger):


    But notice that if you right-click on that thumbnail, you'll see the full image as it existed on my disk (larger than a thumbnail, but not a BIG photo, simply because the photo I chose was 864x578 pixels, or 65kb);

    when I did that with your photos, the right-clicked images presented were the same size as your thumbnails.

    Method 3: subscribe to a photo album posting website such as photobucket or shutterfly (there are others) and upload the photo to that website, then post a link to the photo on the photo-hosting website, like this one:


  3. This looks as though it is a match for your motor & transmission... but it's expensive and has a lot of watchers:


    You could make an offer. If you don't get it, at least you know what you are looking for.

    As a last resort, some plating shops that specialize in plating parts for older cars may have the ability to repair pot metal and aluminum castings (but that won't be cheap, either).

  4. Just for grins, I did a Google search on the paint issue and came up with this (see page 413):

    More Than They Promised: The Studebaker Story

    by Thomas Bonsall (pages 414 & 415)


    It says the Ditzler Deltron urethane paint wouldn't properly bond with the Avanti fiberglass

  5. The explanation I heard was the new body composition required far more cure time before any primer or paint to be applied. The lack of time for the chemical solvents to come to the surface and evaporate meant any coating applied would lose adhesion and come off.

    The story I remember hearing was that they finally tracked the problem to minute quantities of compressor oil leaking into the compressed air piping system used to power the paint guns.

  6. Where is the antenna and antenna cable routing?

    My '71 antenna is on the left rear fender, isn't yours?

    It extends down into the trunk and is accessible from inside the trunk (although it may be difficult to access the antenna cable's attachment to the mast).

    The antenna cable travels (inside the car) beside electrical cables in a narrow channel in the floor beside the left side of the driveshaft hump, crosses to left at base of fuel tank shelf behind the rear seatback, and enters the trunk via a hole just to the inside of the wheel well, about 8 inches or so below the package shelf. I don't think there are any junctions in the antenna cable,

  7. Chuck: "replaced the old motors (both of which had cracked magnets that stopped them from turning) with Dorman motors out of a Ford truck for $35 apiece,"

    More precise info would be nice... what year & model Ford truck, or a part number from the Ford motors? What sort of modifications were done with the Dremel tool?

  8. RQB3263 ...I received the radiator overflow tank caps today and of coarse they fit perfectly ...Many thanks to Charles Peckham of Middletown, RI...best wishes to all for a happy holiday and Merry Christmas....BILL RQB3263

    Also "I'll be using the caps sent to me by our contributor"

    Wildfeir, how about letting the rest of us know what happened here... did "Charles Peckam" (whoever that is) just happen to have a stash of old caps and contact you via private message, or is there a source you should be letting the rest of us know about? Sheesh! ff that's what happened, and there is no source for new caps, say it, don't leave the rest of us wondering.

  9. Finding the cap alone may be a real challenge.

    1) Can you see if there is a pressure rating on your old cap? (if so, my guess is 7#) If you can, you might try taking it to a NAPA store to see if they have anything like it.

    Some of those Radi-Acc overflow reservoirs did not use a pressurized cap with a venting nipple, they just caught a certain volume of overflow vented by the radiator cap

    and the excess beyond that is vented from a nipple near the top of the reservoir.

    2) If you have the Radi-acc overflow setup, here's a possible source for a new cap


    Looks like they may only sell in bulk, but perhaps they can point you to a retailer that carries their line.

    3) Hard to tell from the pictures whether these are the same capacity as the one on the Avanti (about 2 1/2 quarts), but they look very similar and aren't terribly expensive...



    4) try Nostalgic Motorcars to see if they have an overflow tank for your '81

    5) if the cap is just plastic and has no pressure vent/spring and outlet nipple, measure the diameter and see if there's anything in the supermarket that has a similar cap (lemonade, iced tea, etc)

  10. New radiators are available from vendors, but expensive: http://www.studebaker-intl.com/PDF/Cooling.pdf

    Check these prior discussions of the topic:



    And, I downloaded a more through write-up by Avanti83 back in 2013 that I'll be happy to forward to you if you'll send me a private message with your email address.

    He used a 19x26 generic aluminum radiator.

  11. Any suggestions for sources or fixes?

    Today I was looking through a stash of Microsoft Word documents I've saved over the years, some of which are Avanti-related, and I came across this (perhaps it'll be of some help)

    I'm not sure whether I wrote it, or if I found it somewhere...

    Thoughts on checking a bad tachometer on an Avanti:

    Luckily I haven`t had to worry about this problem as yet, but here`s a couple of hints and thoughts: start by checking all the wiring to the tach sender and the tach itself for loose or corroded connections.

    The tach sender is a flat cannister about 4 inches in diameter by a half inch high, located on top of the horizontal steel dash support, just below and to the right of the tach head.

    There are 4 terminals on top of it.

    The tach sender gets its rpm timing signal from the negative terminal on the coil to the terminal marked `D`.

    The sender gets 12v from the circuit used for the automatic shifter... this is the 2-amp fuse in the fusebox closest to the circuit breakers... check the fuse and check for 12v to the sender terminal marked `+`.

    There is a terminal marked with the grounding symbol which should have a white ground wire attached... check this wire for continuity to body ground.

    Lastly, there is a yellow wire from the tach sender terminal marked `M` to the brass terminal on the back of the tach head.

    On the tach head there also are 2 black power leads for night illumination bulbs, and 2 white leads for ground for those same bulbs.

    I`m not an electrical techie so I do not know how to check for the signal from the coil to the tach sender `D` terminal and from the sender to the head (yellow wire) but I guess I`d play with the 12v setting on a fuse-protected ohmmeter to see if that picks up any kind of reading at the `D` and `M` terminals on the sender and the brass terminal at the tach head that varies with engine rpm.

    Hope that all made some sense.

  12. Gunslinger, I replaced the stock distributor/coil setup with a GM HEI distributor in my '71 Avanti years ago and found the tach worked fine getting its signal from the HEI's tach attach terminal;

    required my finding the correct GM wire terminal to mate to the HEI tach (and I replaced the pink resistor wire to the distributor with a normal wire as part of the swap).

    Can't say for certain, but my guess is that the Crane output signal is probably the equivalent (an intermittant 12v signal, same as a points distributor) and would probably work if he had a working sender.

    One possible way to find out if the sender works might be to run a wire from the tach terminal of another running car (either points distributor or HEI) to his sender's input wire (with Avanti ignition on).

    My guess is that his tach will register if the Avanti's sender and tach are both good.

    There may be a way to use a multimeter to check the output of the sender, but you'd need a known good Avanti to find out what the reading should look like... my guess is that the sender

    puts out a variable voltage signal.

    Beyond that, he'd probably need to swap parts with another Avanti to find out which component is bad, or as you suggest, swap out the old speedo & sender for a modern electric tach setup.

  13. Thanks for sharing. I don't remember that article, but I did have quite a bout with the passenger side window on one of my Avanti's years ago; you could actually see the door panel bow inward when the window was operated, and the inner door fiberglass panel was cracking in several places from the power window repeatedly flexing it, and some of the bolt holes were elongated.

    I made some 1/8" sheet aluminum brackets and spacers contoured with a jigsaw to fit within the recesses of the inner door panel's contours (and used the window mechanism bolts to anchor them to the fiberglass). Those brackets tied the various window mechanism attachment bolts together to stop the bowing, spread the force loads, and hopefully keep the panel from developing more cracks.

    I think that was back about 1982, long before I bought a digital camera and regrettably I didn't document the repair. I'm pretty sure I subsequently sold that car (I've owned 6 Avanti's over the years, and can't always remember what I did to which car).

  14. 84 to 86 Jeep Cherokee interchange nicely as I recall. Probably most Chrysler cars of that era used the same thing.

    I went through my power windows in my 73 and they've been working just fine since.

    Could you elaborate on those statements, please.

    1. What year Avanti's do those Jeep Cherokee motors interchange with? (if there's a substitute for the '63 through the 1970's PW motors, I'd like to kow that)

    2. What did "went through my power windows in my 73" consist of doing?



  15. The 5th gen Camaro is HUGE, that would look like a Moo Moo on Tayor Swift ....


    Tom, just for fun. I looked up the specs for Avanti and for current Camaro, and they aren't all that far apart:

    Avanti is 192.4" long, 70.3" wide, and 53.8" high

    5th gen Camaro (2010-15) is 190.5" long, 75.5" wide, and 54.2" high (extra width might allow length to fit OK)

    3rg gen Camaro (1982-87) is closer at 192.5" long, 72.8" wide, and 50.2" high (probably a better fit on Avanti than 5th gen, but either might work)

  16. Anyway... nobody locally seems at all interested in re-brazing the bung onto the tank. In lieu of not finding someone that can do it.... suggestions?

    Anyone having luck with JB Weld?

    Thx, Brad

    Is their concern that the tank could explode or is the tank just in a really corroded condition? Have you tried the local radiator repair shops?

    Seems to me there's not much danger if the tank is thoroughly cleaned (and perhaps coated internally), then turned upside down and filled with water before brazing the fitting back in,

  17. As I understand it, gelcoat is a way of sealing rough fiberglass surfaces to keep the glass fibers from breaking/working loose from the surface, particularly after panel repairs that necessitated cutting into the panel surface, to make a tough, smooth, solid surface for the paint to adhere to.

    I've not had personal experience with gelcoat, but it can be done in 2 ways: spray it as the first coat in the parts mold (after waxing the mold for hand-laid fiberglass parts) when the part is made, or spray it onto an existing bare fiberglass panel to seal it before painting. I don't think gelcoat is used in press-molded parts, only for hand-laid parts to give a smoother outer surface (since the mold is smooth, the gelcoat comes out smooth). If gelcoat is sprayed onto a fiberglass panel to seal it, it results in a somewhat rough surface and needs to be block-sanded smooth when it dries, before applying primer.

    I do not think either Corvettes or Avanti's had gelcoat applied to them by the factory (their panels were press-molded).



  18. The problem with Blake's paint system was not just the paint. The new body composition required a far longer time to allow chemical agents to come to the surface of the body and evaporate than the fiberglass they had been using.

    I thought I'd heard the '83 paint problem had been traced to oil leaking into the compressed-air system that fed the paint guns.

  19. I cannot claim any expertise in this area, but here are my thoughts...

    The rear axle in your Avanti is likely a Dana 44 unit. I doubt that the 56 Chevy used a Dana 44, and if it did, that it would simply bolt into an Avanti.

    (Dana is a company headquartered in Detroit that manufactured differentials for various auto makers, and the 44 is a design they probably supplied in various configurations... axle housing lengths, spline count, spring mounts, traction bar mounts, lug sizes, etc depending on the application, but the basic dimensions of the differential gearbox should be standard, I think).





    There are suppliers offering positraction units for Dana 44 axles...



    Or, it might be possible to find a dana 44 axle for another application (dunno if 1956 Chevy fills that bill) that can be adapted... chances are that the

    mounts and axle-axle width and axle length may differ from the Avanti.

    Your best bet might be to visit a shop that specializes in servicing differentials and see what they'd recommend.

  20. Some Bendix wheel cylinder kits came with the car but I am afraid that the cylinders are pitted. I haven't got there yet but was wondering how one would hone them smooth if the are pitted.

    A picture of the caliper showing cylinder/piston on each side attached.

    Sorry, Unfortunately I was not able to send picture as the file was too big.

    The single-piston systems in local parts stores are likely for later model Avanti's with Chevy chassis.

    The solution you choose will depend on your mechanical skills, or the willingness of a local mechanic to do the work.

    In my opinion honing is a job for a machine shop, and may or may not work, depending on the depth of the pits.

    Pitted cylinders can be re-sleeved with brass or stainless, but sleeving is about as expensive as buying new cylinder assemblies (probably around $500 or more for 4 cylinders, plus shipping).

    New wheel cylinders can be found (increasing in cost) in original, or a slightly larger diameter, or cast from stainless steel.

    Lastly, as stated by Avanti83, you can convert to a system that uses more modern components (probably near $1k in parts)

    http://www.applehydraulics.com/brakes.htm(call or email them for sleeving cost for the unusual Stude cylinders)



    http://www.studebaker-info.org/steeltechinstall.html(but I don't think Steeltech still exists)


    As stated by Bob, SBCA96 has a nice front-brake conversion alternative, assuming he still offers it... he sells front brake brackets he designed, and specifies the parts that you have to purchase over-the-counter (rotors, calipers, hoses, etc); there is some machining required on the Stude hubs.
