Repainting 73 340 Duster Vinyl Yes or No?

Interesting. A stripe delete 73 340. Don't see that too often.

Personally, I feel the lighter color Dusters look better sans vinyl top, darker colors are complimented with the vinyl top. I had a T9 Chestnut metallic 74 Dart Sport that looked good with the black vinyl roof. Ultimately, it is your choice.
