MoparMatt, I'm confused. Do I understand that you intend to use "Dart" lines on a '67 Cuda? It depends on how one defines "Dart". By the '74 model year, "Dart" and "Dart Custom" referred to the 4-door sedan.

Actually the Dart 4-door sedan and the Swinger 2-door hardtop were on the 111 inch wheelbase. The Dart Sport (Duster twin) were on the 108 inch wheelbase.
