Grille swap (Questions)

I have a 75 Valiant Brougham and I wanted to replace the grille and hood to go for more of a Duster look in the front end. Now, I have a hood from a 72 Duster with scoop, but I wanted to know if the grille would be compatible, or if anyone has one that is. Nothing wrong with my old Valiant grille but I like the Duster grille better. Any info would be appreciated!
