I've got the left side almost done. The quarter is about 80% on. I used a 67/68 outer wheel well and then notched the frame moving the inner all the way to the frame. I added about a 2.5 inch strip of metal onto the inner well. I had to weld the seam between the rocker and quarter (but wanted to do this anyways). Someday I am going to try to write up the entire procedure. It has all been a big experiment.
