Last help request. This master cylinder appears to be GM. I am not good with GM stuff. I think the Booster is stock, but once again I am not sure. It appears to be 8 inches in diameter. There are no identifying numbers on either. I tryed to call SACC but they do not answer the phone. They are probably on lock down.
While I am at it. Any suggestions on which Master to get? SACC has several options.
