    Try something like a 65 Chevy truck with a V8. They made 420's for ~20 years behind i-6's and V8's. It's nothing to be specific about.

    The SM420 was the standard 4 speed truck trans in Chevy's up until 1967 I think. Try NAPA or some other "real" parts store. Ask for a clutch for an early 60's Chevy with a V8. There may be a "heavy duty" option there too. Those are the 3 finger style with heavier springs. Personally I'd avoid that and use the standard diaphragm spring style. Much smoother operation and easier on the the left leg and linkage type things.
