I'm guessing these are from a 2 door formal, but honestly I have no idea. I'd also wager that the one with more of an arch is from the drivers door. Once identified I intend to post them in the for sale section.
You might want to check the length of those and the 74-7 Imps and the 76-78 NYB's. The ones that are shown are a little shorter than the later Formals!
