OH and I don't use shims behind the pinion bearing. I have seen them have a nasty habit of coming out on decel at 8600. Shim behind the rear pinion bearing race & case.

Heat treating from Tom's Differentials was the best mod I ever did. We ran 6.14s in our 283 station wagons and the heat treat doubled pinion life.
