Parts ID help, cuda fuel filler tubes and tank straps

Thanks guys, much appreciated. I knew their was differences in straps and tubes just wasnt sure what lol.
Didnt know gasket was different tho! I'll be looking into that, I have a used one I'll check out.
Thanks again!

Straight one is notch back convert,

Straps: 67 had one strap side-to-side. 68-69 had a pair of straps for and aft. Changed it so they could more easily fit dual exhaust.

Yeah, Barracuda FB filler necks are different. So is the trunk floor and the floor gasket.
