Bolting Down The Bed I used 1" spacers under the bed to raise the bed so the steps will be flush with the bottom of the body. This also raises the bed such that the indentations on the back of the cab are hidden. This may have been needed as a result of the bed being a 67-72. That's the way it was when I bought it and I swapped the fenders and steps for the correct ones for the truck. This is a photo of the rear bed support, it is not stock. I fabricated this mount during the rear frame changes when I did the frame mount gas tank. Close quarters back here due to the location of the modified roll pan.
