How can I find out what size clutch plate is on a 1964 Lemans, without taking it apart?
Just checked rockauto.com. Looks like the two V8s are the same. The L6 (inline 6 cylinder) shows a different part number with a 10" clutch. I've bought from rockauto many times. They're usually pretty good. Even with the older stuff. They have excellent customer service as well. HTH. -Jim
Pontiac used the same clutch on all 389-400 engines from 1964 to 1972. Its a 10 3/8" disk, 10 spline shaft. Do yourself a favor and purchase a new pressure plate as well. Ames Performance has a kit #R165P that has everything you need except the pilot bearing. They will also be happy to assist you if you have any questions about the repair. Good luck!
