Helped rid the vib problem.

Fit was good and added a little extra pinion angle. It seems to have fixed the slight vibration @ 65 mph that I had.

Can these be used in conjunction with lowering blocks? Would the pin on the top of the lowering blocks be long enough to protrude through these shims and into the hole in the axle housing bracket?
