I purchased the 6 degree shim kit I posted, the kit came with new hardware and a shoulder washer to make up for the thickness of the shim and still allow the pin to fit deeply into the axle hole. The pin were larger diameter, 3/8 in instead of the factory 5/16 in, had to do some drilling but didn't mind using a larger pin.

I'm also doing the hydroboost swap. I got an assembly off a 01' GMC Safari 3/4 ton van. I'm just now fabbing up the mounts for that. I would like to see what you come up with.
