Go to Tom Woods home page and halfway down right side grey banner labeled Technical Information and Sponsors. Open that and start reading. It has more than you want to know about drive shafts and pinion angles.
Pay close attention to two pictures of the drive shady angles.
Without an SYE and double cardon joint shaft your pinion angle is level with the T-Case. With your lift kit I bet you had wedges on the rear springs which have you pinion angle up.
Get a magnetic angle finder at a hardware store and figure out what you have and then go from there.
