Yes, in my view the FFR rear fender shape is more "angular" than some of the others. As I also said above , it's not just the fenders but the rear deck slope.

In addition, setting aside the FFR, which is generally attributed with that look (per Computerworks' response above), among those types generally credited with being more original, some are "perkier" than others.

That's more than I have to add on the subject, but the most important thing I think I said above, is that every "expert" will have a somewhat different opinion. Stop worrying about it so much and just buy the one you like the best!

In the end, it really doesn't matter. Unless, you have an original 60's CSX 2xxx or 3xxx, (that hasn't been incorrectly restored) everything else is a more contemporary reproduction.
