Viper i am in a similar situation. did a 3" lift with a 1.5" lift boomerang, pinion is up from stock height. T/C is still level. have vibes and clunking i didn't have prior to lifting.going out tomorrow and buying some flat stock to make a 1/2" T/C drop and according to my bad calculations lol. should fix it.you say your pinion id 2-3 deg above driveshaft, pull your 1" drop and try a 1/2" T/C drop, cheap and easy to make and may fix yours also. 1" T/C drops are the norm. jeepwires article on pinion shows you what angles should be with and without a T/c drop. doesn't mention it should be a 1", 1/2", just the angles needed to make it work.
