I will be changing my whole rear axle in a few weeks. Got a great deal on a brand new one with alloy axles and lockers that I couldn't pass up.
So when they come in (about 3 weeks) my current one will be available. In pretty good condition, the only thing that has been changed is the shock mounts, and they were just moved lower on the housing. Has 3.73 gears in it now if you were curious.
I'm in Ventura county.
