an 11" astrovan clutch disk will work on my 62, 3/4 ton, 235six, T5 trans upgrade IF i have a 168 tooth flywheel. what's the easiest way to determine the size if my flywheel? did all 62, 3/4 chevy trucks have a 168 tooth flywheel?
also, will i have to change my pressure plate to match the astrovan clutch?
