I've been getting my AD rust repair panels from this outfit. I did not buy doors but he's shipping doors (and almost everything else) for free. Parts I've received have been from Dynacorn and TriPlus (relabeled "KeyParts") and were well made with pretty good fit. But again, I did not buy doors so I can't speak to their fit.

I've bought a lot from Jim Carter and plan to buy more. Great outfit imo. Some really hard to find parts and good deals.
