How many access holes are in the axle flange?
-if only one access hole, the axle is a '70-72 Pontiac 8.2 axle, and you know what you need. This style of axle is not that hard to find & as A9 bearings next to never seize, as such the standard duty 70-72 Pontiac 8.2 axles are relatively easy to find used, the hot forged versions found in '70-71 HD SST Pontiac 8.2 rears are another story, if missing, next to impossible to find, best to just call Moser & buy a quality replacement set.
-if there ar 3 or 4 access holes in axle flange, the axle could be a '71-72 8.5 A-body axle, it could also be a '70 Type "O" axle, or a '70 BUICK 8.2 axle. All are different rearends & were assembled new with their own style of axle which used an A9 axle bearing. The 1970 Type "O" and the '71-72 8.5 A-body housings were also built to acceept A10 axles.
Of the four different style rearends/ axles listed above there are actually 3 different pitch 28 spline axles. One can't simply install the common '71-72 8.5 Abody axle in the 8.2 Pontiac carrier, it won't slide in. All the above is just one reason, there is no such thing as a BOP 8.2 reared, that unfortunately is a term bred from ignorance & repeated over...
Feel free & post back with how many access holes & I can further identify.
