Ok I want to pick up a used posi unit to get installed, how do I determine what rear is under the car?
it is a 72 6 cylinder car powerglide
10 bolt
Has the two little nothches or humps on either side of the pumpkin
The car is completely stock.

So I would assume is is a 8.5 rear with 28 spline axles, is there a way to confirm this without dissassembly to buy parts?
