The Cragar 13" wheels were an option, regardless of body style. My original '65 Dart GT had them as an option. Dart Chargers had the logo inserted in the cap, or the caps were made especially for Dart Chargers, Ulf would know. Nothing on your car that I've seen came from a Dart Charger. I believe the V8 emblem was placed on '64 Darts. GT's had no exterior
engine identification emblem in '65, which has always seemed odd to me.
