This rugged bracket is made from thick 10 gage steel and powder coated matt black to match your frame. It mounts easily under the left side axle nut. The bracket thickness is the same as the original washer. You won’t need the washer to allow the cotter pin to be installed. The holes in the top of the bracket match our tail light. They are 1 3/4″ apart hole to hole. The holes will clear 1/4″ mounting screws. It also comes with the black license plate frame.
