moved the '85 GM pickup bed (off the truck presently) from the storage spot out back to up front of the shop here..flipped it up on end with the forklift and started to assess what needs to be done to bring it back..was going to sandblast the underside and get a coat or two of paint on it but found the bed under rails are rotted out, have to get a price Monday on some 2"x3" 1/8"thinwall rectangular tubing to replace the rails with. The rails go from side to side across the frame to support the bed floor,spotwelded to the floor, easy removal just drill out the spotwelds
