I got a customer with a 56 Cadillac That needs some third member parts and was wondering if a 57 would interchange? I know that the yoke is different, but as far as the ring and pinion and third member would that be interchangeable? I figure somebody with a parts interchange book would know. Thank you very much
from Hollanders.... this is in the section about the Carrier Assembly (third member) 56 and 57 are each one year only. And this is the section about internal parts, such as gears, etc. Good luck!
