Valiant front clip swap?

Anything but a Barracuda can be used, and everything will line up just fine.

75slant6 is right about the ‘70-72 Duster front, the Valiant fenders are the same as the Duster fenders so the parts list is shorter- hood, hood latch support, grille, and probably the fill panel.

For a Dart front clip you’d need all that plus the fenders and bumper, and swap the lower fill panel for a valance.

The body lines on the Darts/Demon/Duster/Valiant/Scamp are all the same, all of those models are just different by the bodywork ahead of the doors. Just unbolt everything that unbolts and swap it, it’s what the factory did. Heck the door skins on on the hardtop and sport body cars are the same too. Even the inner shell is basically the same, the start the same and then have minor bracket and mounting hole differences based on the wing vent windows. Posty car doors/ 4 door car doors are a bit different but the body line remained the same.
