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

Drop a 350 in so when you pop the hood, they'll forget about the mortal sin of a sharktooth grille being on a 70 Duster.

To me the biggest sin on 1970 340 dusters is putting the 71 340 side stripes on them with the 340 on the rear quarters.
I much prefer the factory 70 340 stripes. Not as gaudy and one year only.
Swapping grills is much less of a sin…lol
