My one Ford was easy, just pull the oem bed bolts but Chevy I think you just measure a couple inches back from the front of the bed and square it up and drill through the bed. I would use some type of plating underneath, maybe 1/2 thick steel plate. I know a guy who just used washer's and it started pulling though.
