  1. I've owned older Corvettes and Avanti's and I believe the wiper arms are the same type of design. The wiper arm slides onto a splined post/shaft and has a spring "tang" that keeps the arm firmly attached to the post.

    My recollection (haven't done it in some time) is that the easiest way to remove & reposition the wiper arm is to use an inexpensive special tool shown below; ensure the arms are parked, fit the tool in place, note the arm position, carefully squeeze the tool handle and the wiper arm together with one hand to release the spring "tang" lock, keep the hand pressure on the tool and the arm and carefully jiggle/pull/guide the arm straight up & off the pivot shaft with fingers of your free hand, then rotate the arm to the park position you desire, and slide/re-seat the arm back down onto the splined pivot shaft.

    ...the technique is shown in this video: https://www.youtube.com/watch?v=eKvbtxGiI_w

    You can also use a flat blade screwdriver, but you will find it difficult to keep the screwdriver properly positioned beneath the edge of the slip-on wiper arm while simultaneously pulling the wiper arm straight up off the pivot (and there's danger that you may unintentionally mar the paint or damage the arm if things slip... protecting that area of the body with something like fender protectors is good insurance no matter what technique you use, and a patch of electrical tape atop the wiper arm at the post to protect it from scratches).

    The tool is available from AutoZone and probably most other local auto parts stores (worth the price, and works well if used carefully, despite the single bad review at Autozone), or buy it from Amazon for a buck or two less (search on "Corvette wiper arm removal tool"), or ask your gearhead friends if they have one you can borrow.


  2. Sounds like your master cylinder (M/C) has been leaking into the booster; brake fluid is incompatible with the booster diaphragm and will damage it. I use silicone brake fluid to avoid this sort of issue.

    If the M/C bore is not corroded you may be able to buy a kit to replace the seals, but chances are the bore is corroded and the cost of a new M/C is reasonable.

    Studebaker International lists the M/C at $96.50 + shipping & tax

    I think the closest replacement for the M/C is a Napa NMC-P1955 ($92 new, or $50 remanufactured + your old core) but you may have to use a  pipe-thread adapter for the (rear brake) line coming off the front port. I did that on a 1980 Avanti.

    The booster can be rebuilt: http://boosterdeweyexchange.com/  I recommend them. They may also be able to rebuild your old Master cylinder

       or there are other rebuilders for master cylinders, for example:




  3. Gene, thanks for reminding me, I need to update this thread. As I stated, I was asking the questions for a friend who recently purchased an '82 that was missing the reservoir.

    I had suggested some vendors for him to call and he was slow getting around to it.... he did find and purchase a reservoir from Dan Booth at Nostalgic Motorcars, for a fairly reasonable price considering the rarity. He said they do have more in stock. I have not personally seen his new reservoir, but he sounded pleased with it. I'll see if I can get photos to post here (he's not very tech-savvy, so I'm not sure he can send me photos).

  4. I can only answer generically, b/c I'm not sure which motor the 1983 Avanti used... Nostalgic Motorcars could probably answer that question:  248-349-4884 

    Here is an article on the original P/W setup, which was still used in my 1971 model; I know it was changed at some point


    The original motors were used on the cars below and can sometimes be found on eBay, but they're usually pricey.

       1960 Ford/Lincoln part # C0LF-14553-A, or Bosch # M 05810. Ford station wagon tailgate window motor C0LF-14553-B may also work.

    If the issue is a simple internal motor failure, a motor rebuilding service might be able to make repairs (many cities and large towns have electrical motor repair/rebuild shops)

    Here's one Avanti owner who innovated: https://studebaker-info.org/Avanti/Tech/PWIN/nollerpwinp0913.html

    I also sent you a private message.

    Good luck and please let us know what motor your car has (part numbers & pics, please, to add to our knowledge) and how you make out with repairs.


  5. My only thought is that its not rocket science, the cable is apparently not fully seated/inserted at both ends (almost has to be the speedo end), or it is broken somewhere in between (unlikely since it worked before the cable was disconnected). It might be easiest to ask a shop to fit the cable from beneath, with the car on a lift, that is, remove the speedo cable at the tranny, push & turn the cable at that end until it seats into the speedometer, then re-insert/reconnect it at the transmission end.

  6. Yes, if the rear seals (O-rings) on the master cylinder piston leak, the fluid can be sucked into the booster and attack the bladder. If you are using silicone brake fluid, the booster bladder may not be damaged, but the master cylinder still needs to be repaired/replaced.


  7. Did you try Nostalgic Motors? How about a want ad on this venue?

    I bought one from Nostalgic back in the mid 1980's. But it is not stainless steel. I think I paid in excess of $400 for it at the time, because they were rare even back then. It was meant for a later model (provisions for a filler pipe intended for unleaded fuel), the only type of tank available at the time, so it would probably require some filler-related alterations for use in an earlier Avanti. I haven't used it yet, and probably won't (I live in CA now), because I've long since sold the Avanti I thought might need it some day. Perhaps you'd like to make me an offer (offline).

    Or, there are "universal" fuel tanks available that could be researched for size and modified by a radiator repair shop to add/swap-in the external "plumbing" needed by the Avanti. For example: http://www.yogisinc.com/index.cfm/page/ptype=product/product_id=13671/category_id=2566/mode=prod/prd13671.htm

  8. Here's a reply I got from Ischuc last January when I had the same issue (but its a shame to lose content, since others may be searching old posts to answer their questions):

    "Try clicking on your user name at the top right corner of the web browser, and then select "My Attachments" from the drop down menu.  You should then see the list of all the images you have attached, and should be able to click on the topic title at the right side of the list and delete the topic, or at least delete the images  you attached inside the topic"

  9. I buy pads from Nostalgic in Michigan: 248-349-4884 (I had bad luck when I tried some from a local parts store)

        ...I expect they also carry front wheel cylinders and/or rebuild kits

    You can also buy parts here: http://avantiparts.biz/brakes/?sort=featured&page=1

       ...or here: https://www.parts123.com/parts123/dyndetail.pta?catalog=0001003a&uKeY=AARCZ

       ...or here: https://xks.com/i-7084309-jaguar-front-wheel-cylinder-2-1-8-square-pads-8777.html

    Or even rebuilt calipers (core trade or outright): http://avantiparts.biz/brake-caliper-disk-brake-pair/

    Here is some good info: http://www.studebaker-info.org/Tech/Brakes/calipers.html

  10. Just a rant, but I did a web search on this company to see if they have a website, and it seems they only use Facebook. I can't understand why businesses do that. I do not have a Facebook account, nor do I want to pay to open one just to access a business page, and I'm sure many other computer users feel the same way.

  11. Thanks very much for the pics Steve, I appreciate you taking the time to do that.

    Kinda hard to believe it would be Avanti-only. But, it does seem to parallel the shape of the cowl in that area.

    Do you know how it fastens to the cowl?

    Does the tube go into the body through the same hole as the wiring harness?

    Is there anything other than a short tube going from the cap to the bottom of the reservoir?

    Do you know where the pump for the wiper fluid is located?


  12. A friend just purchased an '82 Avanti that's missing the window washer reservoir.

    Can someone tell me the source of the original reservoir (model & year car)? I am thinking it may have come from a 79-82 Corvette, but I'm not certain.

    If you don't know the source, could you post photos of yours in the car?

    I'm attaching pics of a reservoir used in 79-82 Corvette.

  13. So, you've looked at the mechanism with the headliner removed?

    Not sure anyone can help without more information; you blame a worn worm shaft or bar, but have you really proven that? Seems unlikely the worm shaft is worn out, more likely something else attached to it is worn or something is hung up.

    Was the problem slow to develop, or did it just happen one day?

    What are the symptoms (can you hear the motor run? does the sunroof try to move at all in either direction?)

    How do you know its not just the coupler between the motor and the worm shaft transmission (or between that transmission and the threaded rod) that has failed? Or the "nut" that connects the sunroof to the worm drive? 

    I haven't personally repaired a sunroof, but it seems to me a worn worm shaft is unlikely.

    There are businesses that repair sunroofs, but the issue may be getting (or making) parts for a long-discontinued sunroof.

  14. I agree, in principle, but good luck finding it, and why start a new thread each time a newbie asks for basic info? I recently had a friend who expressed an interest in Avanti's ask me what engines (cubic inches & HP) came in the various years of Avanti II, since he figured that might narrow down his search. I didn't know the answer, despite the fact that I've owned a half-dozen Avanti's of various years over my lifetime (the memories fade in my old age).

    Wouldn't it be nice if the specs (incl options) for all Avanti II years were available in a format such as the website I posted above? So why not check that website over for accuracy and if you find basic information there that you are certain is faulty, notify the website so that it can be corrected. My guess is that if we polled the members of this website, we'd get a lot of conflicting "correct" info.

    The only valid info I'm aware of is the original order/build sheets, and even they are not definitive; for example, an '80 I owned specified a 350ci Chevy engine with HEI ignition and a GM Turbo-Hydramatic transmission (see below, the only build sheet I remember getting with any of my Avanti's). No horsepower/torque (or curb weight) given. I once owned a 1989 model (bought used) but didn't retain what little paperwork I had on that car. A collection of order sheets from each model year would be a good source of information, and that's something we could probably put together here on this website.

    Anyone know if the Avanti magazine has ever published a list of Avanti II specs by year?

    Actually, it just occurred to me that the book "Avanti" by Thomas Bonsell may have good info, but my copy is an early edition with limited info, having been published in 1979; Amazon currently lists 6 used copies of "Avanti" at reasonable prices and 1 new copy at an outrageous price ($860); but it's not clear which editions these are. There is also a listing on eBay for a late edition. The later years (after 1978) remain the years we have the least information about.

  15. Studegary, why not help them correct it by giving them feedback that corrects the errors you found?

    email them at:  ask(at)automobile-catalog.com

    ...or perhaps you know of a better source to get this sort of information by model year; if so, can you recommend a link?

    the recaro front seats of my '83 need to be redone. i found a site that has the covers but they state specifically for 1980. is there any way to acertain if there were differences from '80 thru '83? at $299.00 a set that's around a grand less than i have been quoted to have them custom made! thanks for any help.

    Why not post photos of your seats? My guess is they are the same as the '80 seats, but that's only a guess.

    I believe the vendor you are referring to is Lseat. I recently sold an '80 Avanti and the new owner sent the old covers to Lseat to use for patterns.

    If your seats look like the photo I'm uploading, then chances are they fit... but ask Lseat if they have a restocking fee for returns (assuming they'll take returns).

    Or, remove the covers off one of your seats and send it to Lseat to have them make a comparison to their patterns (assuming they'll agree to return them if they don't match), maybe they'll give you a discount for giving them both covers if they want the pattern.
