It fits. Well, mostly. My new body is a bit narrower than the old one, I think, but a bit of judicious trimming has the wing fitting OK, so far.
I believe this car would have had “square-cornered” rear fenders originally to match the square-cornered fronts where they meet, but the squares are basically unobtanium these days.
I do think the rear fender needs to be out a smidge at the bottom.
This was the easy side. The other side will be interesting, to say the least.
