I still don't understand why they would be cheaper. When I"m looking at my boards, and the diagrams to cut new ones, you have to cut those doves in every one of the boards, if it's a fleetside, you have to cut around the wheel wells, and on top of that, you have to bolt it down with a LOT of fasteners. All this as opposed to taking a piece of steel, putting it in a bender, hititng a button, then welding it to the sides.
