Diff plugs (Jay Kempf)

I think you would be much better served by buying a good used west coast
subframe with diff intact. Replace subframe bushings and then swap the
whole thing out. Repack the rear driveshaft CV while everything is out.
Just make sure you are buying a 4:11. Not sure what gears the V8 runs.
Anyone know for sure?
