salvage yard names needed

Did you try this one in New Hampshire? I think the owner has a 65 Valiant or two of his own.

The trim you need to replace was used on 64-65 Barracudas and the 65 Valiant Signet. If you replace the fender, the 64-65 Barracuda fender was also used on the 65 Valiant (but not any other year Valiant). I believe the door would be the same for all 63-65 Valiant, Dart and Barracuda pillarless 2 door hardtops (and convertibles), but the door glass may vary with body style and model.

Layson's has the wheel lip molding available in single pieces so you don't need to buy an entire set.

But they don't currently have the rocker molding available. They do however, stock the mounting hardware for the rocker molding.
