1973 Duster to 1970-1972 front clip

Looking to gather parts needed to convert my '73 front end to a "Shark Tooth" grille. Other than the hood, grille, bumper, and valance, what else is needed? I have not had 1970-1972 parts in hand to compare but is seems like the front fenders are the same where the headlight bezels fit?

Thank You
