Parting out a 1995 Z28 Camaro LT1/auto...the rear end was redone at some point. It's a 7.5", the ring and pinion are Richmond (stamped)...does the carrier look like a Richmond posi? It's not the standard Govt-Loc.
I pulled one similar to that out of a 90's Trans AM. It was an Auburn cone style posi. It's in my T now.
