GM 10bolt 8.5" rear diff...most common GM diff pretty much..
That'* what I run in my Firebirds.
It does have 10 bolts that hold the ring gear to the carrier.
A 12 bolt has a larger ring gear and 12 bolts that hold its ring gear to the carrier. That way it can handle higher torque loads.

The covers are shaped differently.
