Not that I'm aware of. EMS concentrates on the parts that are harder to fabricate but it would be nice if their coupe tail pan continued up to the trunk opening for the 35/36 coupe parts. I've seen deck lid skins at SAR but no trunk opening lip or edge parts. I guess we're fortunate that there are any patch panels at all but I don't know how well those fit either.
A good metal fabricator can make the parts with less curvature without too much difficulty as long as they have some good metal forming tooling. If the parts aren't corroded too bad, it may be easier to just replace the corroded area only with fabricated patches welded in. A small patch is easier to fab than a large one for sure.
