73 duster front end swap
@FM3 Dart has it correct.
You can't just "mix and match" grilles from 67-72 with 73-76 cars or vice versa, and you can't mix and match grilles from Plymouths to Dodges either.
Using a Duster or later Valiant grille would be the least amount of swapping, but would still require the bumper, brackets, hood latch support, grille filler panel, hood, and some added bodywork tabs. Using the '72 Dart/Demon grille you have listed requires the ENTIRE front clip- fenders, fender extensions, fender splash guards hood, hood latch support, bumper, bumper brackets, lower valance, and the entire grille.
Fortunately your '73 won't have the shock mount front bumper brackets, so you avoid an entire can of worms with the frame mounting holes.
The Dart/Demon front end is longer than the Duster, so, nothing "mixes and matches" . This is a Dart/Demon hood with Duster fenders, you can clearly see the hood is 2+ inches longer. The whole nose of the car is longer on a Dart/Demon
I've done the swap, and while everything is bolt on you have to source a lot of parts. Classic and Year One would literally be my LAST choices, neither one makes the parts. So if you want to buy stuff, go direct to AMD or order from Summit, as they have better freight charges anyway. But not everything is reproduced, so, you'll need to find a parts car or someone with some used parts at some point.
