  1. I don't know how available these are any more but it was generally accepted that Ford Type F would give firmer shifts and GM Dexron would provide smoother shifts. There are so many formulations of ATF out today I don't know what would be the best recommendation. The Borg Warner Power Shift is similar to Borg Warners used by Fords back in the day so maybe.a Ford Mercon ATF could be a modern alternative. Hopefully someone with recent experience will join in.
  2. Try a National #410059. That's an older number so it may have changed.
  3. You need to get copies of the Studebaker Avanti Parts and Shop Manuals...they have all the information you need. A '67 Avanti is all Studebaker outside of the engine and a few other things. You can find the manuals online or through Studebaker Avanti vendors...in original, reprint or CD formats.
  4. Since you don't know for sure what fluid was in the car, you should get the entire brake fluid system completely flushed. DOT 5 and DOT 3 do not mix and can create an unsafe situation. If you see any cloudiness in the fluid that's a sure sign you have DOT 3 and 5 mixed. I know in 1970 Avanti Motors was specifying silicone fluid (it became DOT 5 later) regardless of what the master cylinder was marked. If Avanti Motors changed that specification I don't when or if that occurred. I believe but again am not sure, that Avanti Motors placed a sticker on the master cylinder or near it specifying the brake fluid to use...but decals under the hood wear away and peel off with time. After you have your system flushed fill with one or the other but make sure you keep it that way.
  5. Avanti Motors used the Studebaker coil spring #526135 for 1965 only then changed...to what and from what vendor I don't know. My information only gives that much on coil springs. Generally a stiffer front coil spring and softer rear leaf spring will help some with the forward weight bias and also improve handling somewhat. That's why I always kept four pounds less air pressure in the rear tires than the front...the handling improvement was noticeable.
  6. The rake was body orientation on the frame only...nothing to the frame was done differently. It was body shims alone. The spring spacers in the front were for cars with a/c due the its extra weight on the front end. I assume it was cheaper and easier than having two different spec coil springs to inventory. The Avanti coil springs are well known for compressing with age which can cause clearance problems with different tire and wheel combinations. If you want to dd or subtract rake...add or reduce body spacers. Just keep in mind if you do decide to give the car more rake you might have issues to be compensated for between the hood and air cleaner as the GM engine does sit somewhat differently than the original Studebaker engine the car was designed for.
  7. No...didn't weigh the car before or after. But the aluminum driveshaft definitely weighed significantly less than the original. The composite leaf springs weighed eight pounds each against about forty-five pounds each for the steel leaf springs. The crate engine supposedly weighed less than the original 350 but how much I don't know. The aluminum intake, water pump, serpentine belt kit all had to have weighed less than originals. The rear seats were less weighty than the originals as was the 700R4 than the cast iron cased PowerShift. The lightweight a/c compressor definitely weighed less than the cast iron York compressor. I'm guessing the car must have weighed several hundred pounds less but the weight loss may not have been well distributed. The composite leaf springs took weight out of the rear of the car but that's where it was needed even with less weight up front. Still...taking weight out of an Avanti is not a bad thing to do.
  8. Removing the sunroof and its mechanism and glassing over the top has been done I believe. I know a fellow (since deceased) who owned a body shop that had an '85 Avanti who wanted to get rid of his sunroof. He bought a NOS roof panel from Nostalgic Motors, cut the roof off his car and glassed in the new, solid roof. I saw the car and the work was outstanding. Doing that is an option. As far as color...let your wife pick it. That's what I did.
  9. Check the cable ends as well...if they're loose or have corrosion build up you can experience the same symptoms.
  10. I used the GM 350HO/330hp crate engine with Edelbrock EFI tied to a GM700R4...it would smoke the tires without meaning to. It took some time to learn how to feather the throttle without at least chirping the tires. I can't say much about the stock traction bars but even though I did what I could to take weight out of the car the front weight bias still showed itself. Cornering was decent but still not up to modern standards. Weight reduction included an aluminum driveshaft, composite left springs, the aluminum case transmission rather than the cast-iron PowerShift, aluminum intake with EFI, later rear seats made from the lightweight materials Avanti Motors went to and any other things I could do. Actually the composite leaf springs took weight out where it least needed to lose weight...the rear of the car. If I had to do it again I would choose either a GM 200R4 for the better spread of gears...the 700R4 has much too low a first gear for a car in the Avanti's weight class and front end weight bias...or I would have gone with a Tremec 5-speed but that would have been a significantly more expensive conversion than the automatic transmission.
  11. Bob... I really can't say...I never thought about it and the car is gone so I can't go look at it. I know the kit replaced both the heater control valve and heater core as well as the evaporator in the console but where it gets its cold air feed I can't say. I'm sure Mike can tell you. Whatever adaptions he made work very well. Bruce
  12. Mike Myer at Myer's Studebaker installed a Vintage Air kit in the '70 Avanti I recently sold. He's installed a number of them in Avantis. I'm not sure if there's a specific kit for Avantis or whether Mike uses components from available kits to work in the Avanti. It's a complete integrated unit...not separate heating and cooling and works very well.
  13. The voltage regulator used on a '66 Avanti with a GM engine and alternator would not be correct for a Studebaker Avanti with a Prestolite alternator. It would be far more easily obtained but its specs are wrong.
  14. Here's what I did for the '70 Avanti I recently sold...this is a pre-cut piece of rubber made for a '78 Corvette that Corvette specialty companies sell. It works just fine and folds up neatly behind the gas cap door.
