66C10LB,
I had to replace the entire length of mine. It was in worse shape than yours. As stated that is the Cab floor and the back wall of the cab. I took a piece that was in okay shape and went to a local sheet metal shop. I had them bend me up a few pieces (8ft in all) with the right contour. I had to replace sections of the inner (floor) part as well. I cut the flange off. Then trimmed the back wall of the cab up another inch. That gave me the ability to weld on pieces for the floor so I was attaching good metal to good metal. I also cut it out in sections to prevent having problems with the wall sagging below where it should be. I cut out triangle pieces and re welded them to get the rounded parts. Sorry I don’t have any pic’s. I’m no pro but it turned out pretty good. I epoxy primed it after and seam sealed the inner part to try to keep dirt and moisture out. If you have more questions let me know. I’ll try to explain it better if needed. Good luck.
