There is no complications with the 3" BL. In fact the reason i installed the B&M in my jeep was to remedy some shifting problems with the stock shifter and it worked like a dream. The shifting is clean, precise, and alot smoother then before. Speed shifting is fun inthe mud and the sand. Just remove the small portion of the floor pan, the 4 bolts out the tranny and swap em out. Remember to run a bead of silicone around the new shifter base so you cant get no moisture in the tranny. And enjoy.
