If you recall from a previous post the door took a beating at some time in the past. I removed the inner door hinge from the main hinge. Then took the whole door apart. Luckily the inner skin on the door was in good shape but the internal door ribs (there are two horizontal and one vertical as you can see from the rivet lines) were bent.
My local metal shop fabricated a panel of anodized aluminum crimped on three sides as well as new ribs. Attached the new ribs to the inner door panel. Then slipped the new panel in through the side that had not been crimped, the bottom in this case. Riveted everything with Olympic rivets in the same pattern as originally constructed. Crimped the bottom. Voila!
Here is the original door panel:
Merry Xmas sweet thang!
