In 1954, GM introduced their new deeper improved stepbed. With this design the optional rear bumper required the license to be moved to the center. This eliminated clearance problems between the bumper and the left side mounted license plate.
To save the creation of a totally new rear bumper, GM placed a dip in their pre-existing 1947-1953 unit. This was necessary to allow for complete viewing of the license in its new position.
The following picture shows the correct bumper with a good view of the license plate. The other pictures are of the earlier bumper on a 1954. Only a portion of the license is visible.
