Here in Phoenix we have a company called Arizona Brake and Clutch Supply that rebuilds just about any stuff that you can imagine, from little garden tractors to cars to semi's. I looked on the internet real quick-like, and there is an Austin Brake and Clutch Supply that belongs to the same rebuilders association. Did you give them a try to see if they have or can get the parts to rebuild yours? They're over on 8151 North Lamar Boulevard. There is also another outfit listed called Triangle Clutch Rebuilders, but no address or city (just somewhere in the great state of Texas!)
And a broken diaphragm spring will easily cause slippage due to low clamping pressure on the disc. Only half to two-thirds of the plate is bearing down on your disc. Your question about 0.080" being enough... yes, it is for a lightweight car like yours. My trucks have all had only had about 0.080" to 0.100" of clamp on a new disc, even the 3/4 tons.
