The Dart and Valiants in Sweden had white or black convertible tops. Was there any othger colors in US or Canada? Did they make convertibles in Brasil , Spain or Argentina?
According to my 65 Dodge & Plymouth dealer Data Books, 3 colors were offered for convertible tops on all models: code 580 - Black; Code 581 - Blue and Code 582 - white. It goes on to say "Black & white convertible tops are available with all exterior colors. Blue is available whenever blue trim is specified or with black trim with blue exterior color". I've got brochures for other countries and none show any convertible models at all.
Added: I had a 65 Coronet 440 convertible that was coded blue exterior, blue interior and blue top and it was a sales bank car.
