Need help with ID'ing a '71 cutlass rear
My friend has a '71 Cutlass that appears to have the original drivetrain. The rear diff cover looks like the BOP 10-bolt with the scallops in the sides, but the rear also has the "ears" on the bottom of the housing that are typical of a 8.5 "corporate" 10-bolt.
Is this a "good" 8.5" rear, BOP rear, or some weird configuration? What would a 350-4bbl, TH350 equipped '71 Cutlass have used for a stock axle?
