I got the whole axle and suspension.
It was out of a 02 C6500 but the axle got switched out.
This project is a later model... I'm asking here because this group seems to be one of the few that actually knows stuff beyond what is listed in the standard replacement pages of the parts store.

Soon (I hope) I will have a 10 on 7.25" bolt pattern disk brake rear end for sale. It has a 4.6 ratio (4.66? 4.62?) and I have gray powder coated 19.5 duals for it.
