Complete tail light swap

Tail-lamp designs change too often, almost every year and between Dart, Valiant, and Barracuda even in the same year. Is that a 1963 Dart? I prefer the long thin tail-lamps on my 1964 Valiant, but different sheet-metal. Those replacements actually look slicker than the factory design. From a GM or Ford? For some, companies are beginning to fab LED replacements.
