the same engineering revisions and upgrades as the U.S. market AMC-built counterparts. Engines were the same as the year before with a one-barrel 145 hp 232 as standard on the sedans and automatic wagon and the two-barrel 155 hp version for the manual wagon. All featured a front sway bar as standard equipment. The 1972 models also included a new plastic grille with a revised hood latch, along with a new taillight design with larger backup lights, a new optional wheel cover design, a third AM radio model (shared with the VAM Javelin), and new interior door panels with a wood imitation rectangular portion. This was also the first year of the seatbelt warning buzzer located above the light and wiper knobs. The Camioneta Rambler American featured the Chrysler-built TorqueFlite A904 automatic transmission, replacing the previous Borg-Warner "Shift-Command" units. 1973 The 1973 model year VAM Hornets were redesigned and incorporated a new front-end design with larger horizontal rectangular side marker lights, semi-square headlight bezels, and a "V"-shaped grille and hood edge. The front bumper included AMC's five-mile-per-hour design, but without the recovering shocks; in their place were regular rigid bumper mounts as in previous years. The automobile product standards in Mexico were less restrictive than in the U.S.; thus, VAMs mounted the bumpers placed closer to the body than their AMC counterparts. The 232 engine was replaced by the AMC I6 rated at gross with Carter RBS/YF one-barrel carburetor, 266-degree camshaft, and an 8.5:1 compression ratio. The three-speed automatic transmission finally became available in sedan models as an option and the rear differential gear ratio changed to 3.31:1 in all units. Other features included new door panels, longer and narrower inside door latches, controls for the cigarette lighter, wiper/washer, and lights knobs had rubber knobs, modified taillight lenses, the deletion of the rectangular "RAMBLER" emblem in favor of "American" script on the rear panel, "258" emblems replacing the "232 SIX" rectangular ones and the removal of the bullseye emblems on the C-pillar base. 1974 The 1974 Rambler American was a carryover. Differences included a new rear five-mile-per-hour bumper and the rear license plate was relocated to the center of the rear panel over the gas filler. The seat and door panel designs were revised. The parking brake pedal received a new smaller rubber pad. The standard wheels were VAM's new 14x6-inch five-spoke design with volcano hubcaps. The I6 included an
