I know that someone has used a 10" clutch and pressure plate from another car with the Corvair. I am trying to figure out what car it came from and whether any modifications (if any) are needed and what they are. I believe there was only minimal modifications needed to the Corvair flywheel for this to work. Thanks in advance for any ideas, Brian Seibenick 66 Monza Coupe NHRA Stock Eliminator
