I recently bought a p case rear axle off a guy that claimed it was a 456 outta a 1962 Chevy. But it has factory leaf spring mounts and correct me if I’m wrong but would an impala be coil overs? It’s out of a model a coupe that was bought at the meltdown drags. It’s def a two wheel peeler but not positive it’s a posi or a spool. My question is how do I identify it for sure so I can order a ring and pinion to rid myself of the 456s. I don’t believe the tag is there anymore Sent from my iPhone using H.A.M.B.
