Anybody have trouble with clearance of the pressure plate forks and the disc. I have an original Borg an beck pressure plate and disk. They had no mileage on them but being i had the motor out for painting, thought I would replace the disk. Bought a new disk from an Avanti parts dealer. I installed it and something didn't seem right. It's been awhile since I installed a clutch and never in an Avanti. But just before I dropped the engine in, I switched it out with mine. I compared them closely when both were laying next to each other. Mine has 5 springs and the Sachs disc had 10. 5 with 5 over. When the other disk was in, I had about 3/16 between the fingers and the springs. There was no way you could depress the clutch without the fingers hitting the springs. My springs were about the same dia. as the inner springs on the new disc. The outer springs were the size of GM valve springs. With my disk in, Clearance is fine. Contacted seller and he said He hadn't had any problems. He took it back. Just wondering if anyone has seen that before.

Thank you for the input. I just bought a set of NOS xr45s and a set of ap85s. For the price, what the heck.

The R2 takes different plugs though. I talked with Jon Meyer the other day and I think he said HR5. Unfortunately the piece of paper I wrote it on got brake cleaner on it and no more writing. I hate to call him back up.

did you sell the plugs

Any recommendations for spark plugs for my R1. Some brands seem to perform better than others.

Those service letters are very informative, thank you again!

I guess the 4 pole bodies are easy to come by.

Thank you for that information. That service letter is very helpful. I guess mine came with the 3 as I am the original owner, car has 39k and starter was never replaced. I was fortunate to have one lying around even though it had a different nose. Had another and think I gave it to a scrap guy that came around last year.

Have overhauled everything except the starter. When I open it up, one of the welded on brushes had rotted off. My starter is a MDU7025 12T. I had another prestolite that has the same body, but noticed when I opened it up, It has 4 field windings and the Avanti only has 3. Anybody have any ideas. Getting down to being able to fire it up soon.

Can you post where you got the valley pan and valve covers?

It certainly is, looks like a factory install. Thank You

Can an R2 be retrofitted with A/C

Thank you, I have a couple of their dealers close by i see.
