Finally got the driveline angles sorted. Reminder: C10 longbed, stock ride height, single piece driveshaft, 5.3L LS, 4L60e, Blackheart engine stands and crossmember Installed 4 degree shims to lower/reduce (down) pinion angle. Reinstalled/used shim that came with the trans cross member. Engine and pinion angle are exactly equal. Driveshaft working angle is 0.9 degrees at both ends. Engine angle is about 3.3 degrees.
