Probably the same 4 nuts and studs that hold the axles in on any other 8 3/4 rear end.

As already stated, you have to pull the drums first to get at any of it.

The main difference is that the hub flange/drum assembly is held on by the nut on the end of the axle flange instead of the axle flange having the wheel flange being forged as part of the axle.
