72' demon grill and headlight bezels

Ditto on mounting the grille on the flange rather than below it.

Check the location of the headlight "bucket brackets". These brackets are the ones that mount on the radiator support and the headlight assembly attaches to it. There's a little "wiggle room" that should allow you to raise the headlamp and allow the grille to sit a little higher.

Also check the hood latch support assembly and make sure the flange is not bent down. Hope this helps.
