I have a 8.5 rear end off a 1972 Olds. Was told it has 3.08 non posi gears when i recieved it. Was going to clean and install a posi and swap it with my 8.2, but I see no means to do so in the near future and don't want to trip over it any longer. Stored in shed or garage for past 8 years. Selling for $100 firm. will NOT ship. You come and get it. I'm in Southeast Michigan.
