1973 USA Bumpers

For 1973, USA models got redesigned bumper-to-body brackets to meet FMVSS No. 215 (2.5 mph bumpers). They also used larger bumper pads. The chrome parts look similar but are different.

NOTE: A 1973 front bumper with brackets does not fit a 1971 or 1972 model

License Plate Lighting

 Also see: Rear License Plate Lamp

For North America in order to meet new FMVSS regulations, 1973 Sedan rear bumper was modified to have a brighter license plate lamp (the coupe with its dual lamps was already bright enough). The lighting moved from the bumper to near the plate.
