Need Help with Picking a Color!!!
I'd favor the rootbeer or some dark brown metallic w/ beige guts if it didn't have the half vynil top.
One of the very few mopars that attends the local Mccruise-in is a Duster identical to yours (less the stripe and spoiler). It may not win fans favorite but it's all original and well kept condition / appearance earns respect.
A medium to dark red might look good on yours. I'd stay away from reds that lean toward purple. My .03 cent LOL
