  1. My 87 Avanti looks as if the front fenders cracked behind the wheel openings and have been repaired. I have been told that Kelly had a problem with cracked front fenders on his early Avanti's. <_<  Is this true and what caused them to crack?

    Exactly where is the cracking (ie, when you say "behind the wheel openings, do you mean inner fender inside of the wheel openings, or wheel opening lip, or the area between the wheel openings and the door, or around a body mount)?

    Most cracking around the wheel wells is likely caused by a poor choice of tire size, resulting in a clash between the body and the tire (hitting a bump while turning into a driveway, etc). You'll know it if that's happening to you, but it may have happened to a prior owner, who then got rid of the tires and repaired the damage.


    Try these insurers, and ask for an "agreed value" policy (as opposed to "actual cash value or "stated value"); note that most of these will have some restrictions, such as minimum age of the car, your driving experience, how the car is garaged, annual mileage, limit you to collector car activities/events; all will require pictures and/or appraisals to certify value:

    Hagerty (800) 922-4050 (said to be attractive when you own multiple collector cars)

    American Collectors Insurance (800) 360-2277

    Great American "Classic" (not collector insurance; will do "agreed value", but no driving to work/school daily)

    Grundy (800) 338-4005

    JC Taylor (800) 345-8290

    Frankly, I've been too lazy to check them out myself, so I can't personally recommend any of them, but Hagerty and American Collectors seem to come up often as insurers of choice for collector cars. Great American will write "agreed value" policy for non-collector cars if the car is not regularly driven to work or school, but the price will be higher than for a more-restricted collector car.

  3. Does anyone know of a trick to make their removal and insertion a bit easier?

    I haven't tried this, but I can envision fashioning a tool out of a short length of rubber tubing and a fat wooden dowel, such that the dowel with perhaps about an inch of tube extending from it's end (glued onto the dowel) could be pushed down onto the bulb, turned, and pulled out; reverse for installing. The tube, of course, would need to be enough smaller than the bulb to grip it. A dowel with a rather small suction cup on one end might be another approach.

  4. Isn't the AII bolt pattern a small Ford pattern?  Does anyone know the stock wheel size and what can fit in the wheelwells?

    What about 17" wheels?  Anyone know where I can find data on what fits in this size?

    Questions coming out all over,



    Can't give you a definitive answer, but here's a few of my thoughts.

    Avanti II (Prior to the Monte Carlo chassis in the mid-80s) uses the stock Ford 15" pattern for early 70's big-block Shelby Mustangs and full-size Fords; the Magnum 500 wheels used on Avanti II's were 15x6, I believe... unfortunately I'm not at home to go measure mine, it's possible they may have been 15x7, but 15x7 should fit, and I'm pretty certain 15x8 would be too wide.

    The fit of the front wheels is particularly tight, and I think 7" may be the widest rim that will fit there; 195/75-15 tires fit without rubbing anything, 205/75-15 may or may not, and 215/70-15 may or may not; larger/wider sizes likely won't. Front tires are prone to hit the wheel opening near the upper forward section with the tread while turning and hitting a bump (like entering a driveway), and rub the frame at the rear inside of the front tires during hard turns.

    Can't tell you for certain what/whether 17" wheels will fit, but I suspect you could find some combination that will. Here is a website where you can play with combinations to compare dimensions:


    But, not every tire has the exact dimensions as others in the same size, and that can matter when tolerances are close.

  5. Hello, could someone tell me what standard size ring and pinion should be on my stock 1987 avanti. It is somewhat sluggish off the line and I thought about changing the ring and pinion gears to help with this. I do not know where to find out what size I already have to be able to shop for different gears. Has anyone changed out gears before to help with this porblem? Help is needed.

    I can't answer directly, but I think your car has a GM 10-bolt differential (count the bolts around the outside of the rear of the differential case) and I would guess the standard axle is a 3.08. You can determine your present ratio by lifting the rear wheels off the ground with a floor jack or two, and with the transmission in neutral, put a mark on the driveshaft and on the outside of a tire, then rotate the driveshaft slowly until the tires make one revolution (someone else needs to watch the tire mark), counting the differential revolutions (better yet, rotate the tires ten times while counting driveshaft revolutions, then divide the driveshaft revolution count by 10).

    I think higher ratios of 3.42, 3.73, 4.10, and 4.56 are available for your differential. Bear in mind that changing the differential ratio will cause speedometer error, and your highway mileage may suffer.

    Any good driveline shop should be able to make the change.

  6. I have a 1987 Avanti convertible. The master cylinder needed replaced, so I purchased a 1987 Monte Carlo master cylinder. It was not the same set up as the master cylinder on the car.  What master cylinder would a 1987 Avanti take?

    I don't know if this info is pertinent, as I don't have an 87 (mine are 71 and 80), but I sometimes write part numbers in my Avanti parts book when I see them, and I have these by the master cylinder entry:

    NAPA 36259 (NAPA parts stores)

    EIS 64874 (industry standard number, brake suppliers/wholesalers might have them)

    Might be worth looking to see if either might be the one you need.

    Or, sell me your car and let me worry about it :>)

  7. Do you have a Stude Avanti shop manual? That has a wiring diagram, and the same harness was likely used for a few years of the Avanti II, with additions for new/different accessories. Unfortunately it leaves out most accessory circuits. There weren't, to my knowledge, any diagrams published by Avanti Motors for the Avanti II cars.

    I've seen the Stude diagrams alone for sale on eBay, in paper color reproduction ($20+ shipping) and on CD ($6 + shipping), but I think for the price you'd be better off with the shop manual since it has much more information than just a wiring diagram.

    I do have a booklet of xeroxed hand-drawn sketches of partial wiring diagrams for some circuits of various year Avanti II's that was put together by an individual "E.J.J. 3rd", titled "Avanti II Electrical Circuits Block Diagrams" copyrighted in 1990 and sold via an ad in the AOAI magazine, I think (about 25 pp). I can't recall for certain where I got it. Unfortunately there is no contact info in the book, and it contains only partial diagrams (apparently sketches the author had made while chasing problems), for circuits like the antenna, radio, power locks, burglar alarm, cruise control, etc.

    You might try contacting some of the parts vendors to see if they know of anything (Nostalgic, for instance)

  8. I'd suggest the older large Recaros, like the ones used as an option in Avanti II's of the late 70's & early 80's. You just need to go to a salvage yard and look around, as those seats (I want to say Recaro "C" seats, but I'm not certain) were used on a wide range of cars, including Mercedes, BMW sedans, Cadillac Allante, etc. If I'm not mistaken, you can even still buy adapters for them new from Recaro for the Avanti.

    Another possibility would be Jag XJ40 seats, which are very comfortable, not quite as firm as the Recaros.

    Here's a link to an Avanti recently on eBay that had Recaros:


    Here are some links to seats now on eBay(or recently sold) :






    Tell us what you're looking for in terms of color and material. I have a very nice pair of Recaro (I think) seats in a very dark brown (almost black) soft woven material that I'm not sure I'll ever use, because I also have another tan leather set (from an Allante) I hope to make use of in a long-term project car.

    One problem with seats is that they are expensive to ship (heavy and bulky) so it's probably best to find some within driving range. Recovering them can be very expensive, too, but may be necessary to complement your car, and new foam cushions may be hard to find.

  9. here's a some numbers I had written down for the rears, but I've had the numbers quite a few years now so I'm not sure they're still valid:

    Koni 8240 (F?) -1012 (502)

    Koni 82-1425

    Gabriel 26177

    Monroe gas 5831

    Sears Classic gas 91103

    One owner reported using shocks for a 70's Camaro by inserting the crossbar from his old shocks into the upper mounting hole on the Camaro shocks.

  10. Here is what an Avanti steering wheel normally looks like:

    http://www.avantiparts.net/UCBlack698.jpg (on a 69 Avanti)

    It uses the "blades" in the two spokes to operate the horn.

    When an aftermarket steering wheel is installed, normally it comes with an adapter hub with a decorative plastic external round hub cover that has an emblem or name of some sort on it, and that center hub is depressed to sound the horn, ie, the hub is a horn button. The adapter bolts to the steering column, the wheel to the adapter, and the horn button/hub cover generally snaps into place on top.

    Nardi Classico is an aftermarket wooden wheel commonly used on Avanti's, it looks like this:


    One of the most common aftermarket wheel makers is Momo, who offers a wide variety of styles; they use the center hub as the horn button. See them at this site:


    (click on "Momo", then "steering wheels", then pick a style from the drop-down list)

    Yet another maker is Grant:


    You may have to remove the hub and the steering wheel to figure out what your car has in the way of horn provisions. If no attaching screws are present, generally the decorative hub cover either is pried up, or you press down on it and rotate it in relation to the wheel to free and remove it.
