1965 Bonneville POSI-traction Help!
Working on '65 Bonne Convertible 421 Tri-Power, THM400, 3.08 open rear end. Looking for a POSI unit and possibly a 3.42 ring and pinion. Best I can tell this is a heavy duty rear end, it has a 10 bolt cover, but it has 31 spline axles, the ring gear is 8.5", there are 12 bolts on the ring gear,and it is NOT a C-clip rear end, it has retaining plates at the ends of the axle housing. I've been poking around the aftermarket but can't come up with anything. Any ideas or what do you have for sale?

I am pretty sure nobody makes ANY internal parts for this rear end. I had my rear end guy look for new stuff for my 66 Catalina (same rear). He said NO ring & Pinion & No posi carriers available. I bought a rear end with a 3.42 posi from a reputable Pontiac guy in Mass earlier this year & picked it up on one of my transport trips. Expect to pay good money for a good used one!
