All 400A Convertible Sedans were produced with a rear bumper. Victoria's came with the same rear bumperette as most model A's.
To change from rear bumperettes to a full width bumper on a 30-31 Model A, just unbolt the 4 bolts at the rear bumper cross brace and unbolt the 2 bumper clamps. Then use the 2 clamps to mount the full width bumper. After removing the Bumperette support between the rear bumper arm and the cross brace, a replacement filler piece is needed.
