They have 1 1/2 " flanges on bottom and back side(so you can access the extra space in body panels with stock interior panels removed) and are simply screwed into bed and the braces that interior panels used to be attached to with Tek screws. I borrowed plans I found on MUD, but being a sheetmetal worker, I used aluminum instead of plywood. At the front where the wheel well gets in the way, I used an .040 alum end so I could trim to fit and pop riveted it to the box.
