72 Duster Sharktooth grill to fit on a 70 Duster possible?

Sin?
Maybe you’re being facetious. To me, if the stuff on your car was at least Mopar related, I’m okay with it.
I hear people complain about painting a 1969 car Sublime or Plum Crazy when those colors weren’t available yet. Some complain when people put late model Hemis in their cars.
Come on, man… why are Mopar guys so uptight about factory correct stuff? Chevy and Ford guys aren’t like this.
People that love these cars come in many stripes. I love some stock stuff but I like to update things where I can to make the car a better driver for me. None of these came with 5 speed overdrive transmissions or 4 wheel disc brakes. None had CD players either but we added that stuff to make the car more enjoyable. Sound deadening, brighter headlights, high back seats, 3 point seat belts too.
