I have a 79 Camaro and my clutch is starting to go bad. Ive been looking on Summitracing.com for a Centerforce clutch but i am not sure what to buy. The car has a 350 and a 4 speed. Im not sure the engine is original but i think the tranny is. I need to know what diameter of clutch to get and how many splines. Thanks

 

If you cannot be absolutely certain of the trans model it is best to pull it out first, then order parts.
Same goes for the flywheel/clutch, any of the parts could be from another car.
