There are 3 different lengths of running boards, obviously, for the 1/2, 3/4, and 1 ton. However the front running board bracket and the bracket at the end of the cab (mounted on the frame) are in the same location for the 3 above mentioned sizes. A rack body uses a short running board that ends at the rear on the cab. This short board only requires 2 mounting brackets (on the frame) therefore all three size trucks in the rack body or flat bed format will use the same short running boards.
