That is a 4 series Eaton posi case. Don't mess with an Auburn posi. They are junk. I have new gears, clutches, shims, cross shaft, retining bolt and all of the other parts that you need to put that Eaton together. You will be limited to a 3.73 to 6.xx gear set with the 4 series. The installation kit has all of the other parts that you need, shims, bolts, spacer... Those are Moser axles in that box, but I don't see any axle bearings.
