When I did the bed swap on my old M35A2C, I used my buddies k-boom. His k-boom in behind the cab of a rollback wrecker. He parked right between the good truck and parts truck. Lifted the old bed and sat it on his truck (his fee was getting the bed) and swung around anf picked up the new bed and moved it right back on my truck. Pretty slick, it was. On the other hand, when I picked up that old M887 in GA the bed was off. Wayne Harris and I used concrete blocks, 4x4s and 2 bumper jacks to wrestle the bed around. Needless to say, the next time I went to Wayne's house, we got his M816 running.
