Duster, Valiant and Scamp all use interchangeable front end sheetmetal from '69-'76. The front end metal was the same from '69-'72 with the exception of marker lights and the front end metal was the same from '73-'76, but with a slightly different styling than the '69-'72 cars. For example, you can put a '69 Valiant grille in a '72 Scamp or a '71 Duster sharktooth in a '71 Scamp, or a '69 Valiant grille in a '70 Duster. Same goes for the '73-'76 cars.
