With lift springs, no shims are typically needed with the stock single-cardan shaft, however, with the 2" longer shackles, you generally need about a 2 degree shim to tip the pinion down:

Getting the Wheeling Fever
good news is the vibration has reduced substantially. But, I'm going to reinstall the shims/wedges again only with the thick end facing the front of the truck. With a 6 degree difference (83 at the xfer case and 77 at the diff.) the shims I have are @ 3/8" thick. That should narrow the angle difference to within a couple of degrees (I hope).
