Rear Axle Parts Needed

[72chey4x4]

I'm trying to find some parts for an Eaton HO52 or HO72 rear axle, and yes I realize that it's a long shot. I need the inner spider gear assembly with the 4 smaller gears, or I'd be interested in upgrading to a posi unit. Also need the hub retaining nuts and locking plates for both sides.

I haven't been successful at finding anything for this axle so far (axle seals, hub and differential bearings, etc.) so any help would be greatly appreciated.

Thanks....
