MyMopar is very close!
Note that I had cut the quarters off a year so ago. See the first pic to see what I was working with.
We first lined up the skin on the car. They actually fit like a glove. Very little work to make them line up very nicely. We used welding clamps to hold the panel in place and laid down the tape to serve as a guide for placing screws and then as a cut line. Note that only an inch or so of the original metal remained. The goal is to screw the skin onto car so that the cut line is a 1/2" or so below the top body line. We drilled pilot holes for the screws and screwed the panels together along top, front, and rear seams. We did this starting at the center and moving out. Next, remove one or two screws from the center and cut through both panels with a .035" cutoff wheel along the tape line. Remember, when you cut through both panels, you are going to have a strip of scrap on the INSIDE of the quarter. I used a cutoff wheel to bisect that first section of scrap so I could pull the scrap out from the inside as I went along. I used the butt weld clamps to keep things lined and the two panels flush. You should make sure to clean your metal along the weld line. I used a wire wheel for this as I went along. I did use weld through primer in the wheel well area. Speaking of which, I use welding clamps to hold the quarter skin to the wheel well lip and drilled 3/8" holes in the skin ONLY and then plug weld the skin to the wheel well. NOTE that I did a LOT of prep work on that wheel well lip, welding up the holes from where I drilled out the original spot welds.
The real art is along the door edge and the tail panel edge. These areas were rough on my car, so I had to do some hammer and dolly work as I went along and I still had some gaps to weld up.
Seriously, you can do this at home! I had never welded before this project! Of course, I did get a lot of practice when I did my floor pans and trunk pans! The quarter skins have been the easiest of the rust repair thus far...by a long shot!
By the way, for those that don't remember, the 2nd and 3rd pics show you the PITA sail panel repair! That required some hand-made pieces!
