In 1974, the wheelbase variant of the A-body sedan was dropped, and the Valiant sedan became a rebadged Dart. The larger size resulted in thicker C-pillars and new rear fender contours. Thenceforth, the only differences between the Valiant and Dart were minor cosmetics. The 1973 Valiant grille and front sheet metal were retained for 1974, but the front bumper's rubber guards were chromed. The taillights were extensively redesigned, resulting in a more formal look. The US Federal bumper standards were applied to rear bumpers for the 1974 models, adding even more weight to the Valiant. Since the Duster (1970), Dart-based Scamp (1971) and Dart-based sedan (1974) displaced both of the Valiant's 1967 bodies, they could be considered to represent a fourth generation of Valiants.
