330,373 sold. For 1973, the vent wing windows were deleted from the Scamp, and all models were given a new grille and front bumpers able to withstand damage at a impact, as well as steel beams inside the doors to protect vehicle occupants in side-impact collisions as mandated by NHTSA. The door beams, the new bumpers and their impact-absorbing mounts, a rubber-booted telescoping system attached to the car's structure, added mass to the Valiant. At the same time, engines were being progressively detuned to comply with increasingly stringent emissions regulations. Performance and economy suffered as a result. Through the early 1970s, the Valiant took more than 40% of Plymouth's total sales volume. These models also had considerable success in foreign markets. Worldwide, Chrysler affiliates and subsidiaries sold American- or Canadian-made Valiants from complete knock down kits, as well as locally designed and engineered Valiants and Valiant-based vehicles incorporating a mix of North American and local design and components. Fourth generation (1974–1976) 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. 1974 Valiant was also available in a "Scamp package" which included 318 V8 engine, four door, three-speed automatic transmission, power steering, power disc brakes, chrome trim, vinyl roof, AC, carpet, split vinyl bucket seat bench, radio, rear window defroster blower, and 120 mph speedometer standard. Production was limited and ordered as customers requested the package, a few hundred were produced. 1974 introduced the Valiant Brougham and its twin, the Dodge Dart special edition. Available in two- or four-door models, they were a compact luxury car meant as an attractive alternative to larger luxury cars following the 1973 oil crisis. The Brougham had generous chrome trim, a vinyl top, deep cut-pile carpeting, velour cloth upholstery, interior
