Thanks, I was kind of hoping for that answer. I believe (hope) the fenders are the same between the Dodges and Plymouth.
One way or another it looks like I'm going to need a fender if I'm going to delete the spare tire well. Either a drivers side to use as a donor for a patch or now If I lucky a passenger side PLymouth fender to just bolt on.
Hopefully as many of these as I've seen that people have gone fenderless on something will turn up.
