I have a 3" BL on mine and it came with a 3" drop bracket for the linkage. It worked perfectly until i added the 4" suspension. The T-case drop is what put mine in a bind and sounds like what the problem is on yours as well. Im getting a SYE for mine to eliminate the linkage problem. Would prolly fix your problem too. Alot of people do the SYE to eliminate vibes in the drivetrain. I dont have any vibes but the linkage is a pain in the arse for me. The bracket from quadratec you are talking about mounts the linkage to the tcase and would prolly fix yours as well. Its a bit cheaper then the SYE kit and driveshaft, but the SYE strengthens the output shaft as well. Kind of a win-win situation. Whatever solution you want to go with.
