How to identify Oldsmobile 12 bolt?
I know the ring gear of a chevy 12 bolt is 8.8" and the oldsmobile o-type 10 bolt carrier is supposed to have an 8.2" ring gear...
BUT... is there any way externally to tell the difference between the 2 rear ends?
What I have here is a rear end on a 69 cutlass a guy is selling.
He's sent me pics and thinks its a chevy 12 bolt. Yes, the case has 12 bolts, but if I know my oldsmobile lore only olds cars built in the oshawa, ontario plant had chevy 12 bolts between 1968-1970. All the olds cars built in america are supposed to have had this strange weak o type 12 bolt that's more like a 10 bolt strength wise.
So can anyone help me out?
