A buddy in our club has a metal roller, so forming a piece of sheet steel shouldn't be too big a task, using the old panel for a template. Most of the quarter is solid except for about 4-5 inches at the bottom.....and I could make the joint under the chrome strip.
Yeah, the driver's door's got a bit of sagittis. The donor car's doors fit and shut really well for as rusted the rest of the car is, but I'll probably replace the hinge pins and bushings.........if I can find them. If they are the same as a Chevelle, they are being repro'ed, I'd guess.
