Ring gear & carrier are out of '64 Corvette. This early style posi is not as desirable as the Eaton (ED 32297) which replaced it.
Often, inside the carrier, one or more corners of the two alloy divider plates (spring locators) will have broken off, not allowing one of the long posi preload springs to seat. If such is the case, the carrier is basically good for parts. Been through this before

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
