Unlike earlier years, the 1960-66 Suburban and Panel Truck rear bumper is not the same as the front on this single body unit.
Two items separate them from the front.

  1. The bumper brace holes are punched in a different place. They have a separation of 16 1/2” on the rear and 19 1/2” on the front. Thus, they cannot be interchanged.
  2. A “dimple” on either side of its center is only on the rear of this Suburban and Panel Truck bumper.

Why the dimple exists is not known. The only reason we have heard: It helps employees on the assembly line from mixing them and slowing production!
