Keep in mind that I also sell steel replacement panels as well as Fibreglass.See thumb nail 8947 below.
Cut the outer steel off about 1 inch below the Alum. trim. Welding in the top of wheel well is still behind outside metal and very hard to get at so has to be done from inside.Remember the wireharness is running along the drivers side. I have seen many burnt or cut by the inexperienced.. If you are putting on fibreglasss rear outside quaters I would recomend fibreglass inners. I sell a 1 piece complete inner unit for $250. Pic 1 shows inner metal in place and painted ready for outer skin to be installed.Good Idea to put a drain plug in the lower area behind tire,note exta hole drilled in front of tire for water drainage into bilage area.2 ok. the white in pic#2 pic is the inner assembly.I had better shots but comp, said they were too big to download. .
