If you are asking about the rear fender-tail lights. Thats a no . What you do is install the left housing in the right fender inside and cut the fender out. You then weld the housing into the fender. I then built pans that bolt on the inside to protect the bulbs from rocks. Big trick was welding without warping. I built this set of fenders 27 years ago with a torch. Didn't have a mig in those days. You do the other fender just the opposite.
