1976 for North America and 1981 for South America. The restyled Dart for 1967 featured a rear window with compound inverse curves. This created a unique appearance at the rear of the greenhouse, but tended to collect snow and created thick C-pillars that looked formal but created blind spots for drivers. Curved side glass was used for the first time on a Chrysler compact. The front featured a new dual-plane front end contour: the center section of the grille, bumper, and leading edge of the hood were recessed from the front plane of the car. The single headlamps were placed forward of the recessed center section, defining the front plane. Park/turn lamps were set into the grille, in the corners formed by the transition area between the recessed and forward sections. With the new design, changes were made to the Dart lineup, beginning with the elimination of its station wagons and the base model's "170" designation. The only body styles were the 2- and 4-door sedans, the hardtop, and the convertible. The base 170 model was now badged simply as "Dart". The 270 and GT versions carried on unchanged for the most part. In late 1967, the GTS model debuted but was built in limited quantities due to its lateness in the model year; the 1968 GTS was, arguably, improved by fitting the new high-output V8 as standard equipment. The 1967 Dart, along with all other 1967 Chrysler products, got a new dual-circuit brake hydraulic system to ensure a loss of pressure in the front brakes would not prevent the rear brakes from working, and vice versa. The system also incorporated a brake system fault telltale on the dashboard. Other changes to comply with new federal safety laws included collapsible steering columns, additional padding on the dashboard and sun visors. Shoulder belt anchors were also provided for front outboard occupants. The 1967 redesign removed all traces of the older Virgil Exner styling that proved less popular by the early 1960s. The newer body was trimmer and proved extremely popular, causing sales of the Dart to surpass compacts from Ford and GM. 1968 Changes for 1968 were relatively subtle. The park and turn lights in the grille were moved slightly inboard and made round. Side marker lights were added to the front fenders and rear quarter panels, to comply with newly introduced Federal Motor Vehicle Safety Standard 108. Shoulder harnesses (separate,
