Do they have any 2003 Explorer Sport Tracs down there? Because they have the only 1L2Z-3551729-AAPTM parts remaining in existence that haven't been destroyed by sun damage. It would save me a lot of time on this project: https://sporttrac.org/threads/gen-1-roof-trim-reproduction.1...
At some point in working on old cars you need definitely need to give up on oem parts and fabricate or buy reproduction things. There is an inflection point where it is less hassle. People tend to overvalue authenticity, I think, so for me the inflection point comes sooner than average. Having read your post... It seems like you have this problem tackled? What's left? Having the shape scanned opens up tons of possibilities.
