HELP Identifying Rear Qtr Panels for Convertible '68 Barracuda

I think I see what you are speaking about ... So in you opinion, will Dart panels work or will it be a significant visual "thing" I'd be obsessing over for years? Also, looks like you did a great classy detail on yours. Could you send me a close-up of that and let me know if it's simply painted, or covered, or what you did there?
I wish I could say I did something creative there but that is just the way they were originally
