73 duster front end swap
I may be wrong, but I think you need to change the whole front clip. If you wanted to add a Sharks Tooth grill, you might get by with using your fenders and getting an earlier hood, bumper & brackets and probably the hood latch support and lower metal piece between the grill and bumper.
@72bluNblu has done this to his car and can probably tell you exactly what you need to do a Demon front end.
