In my experience, clutch linkage (if manual) will need to be adjusted. The lowe steering shaft should be loosened at the rag-joint--the slip shaft can be "tapped with a hammer" to extend to the new-needed length and then reattached to the steering column. Also, I had just installed a steel Tom's Bronco parts radiator shroud, it needed to be clearanced a bit to keep from hitting the fan since it is effectively mounted to the body and thereby shifts position from the lift. My gas fillers were fine. Otherwise, its a simple operation. These other things I mentioned really arent a problem to address. I was amazed at the difference in the ride from the BL...I had no idea how bad my body mounts were...they were translating alot of noise and vibrations. Good luck.
