6 of 10
The support beams in the middle of the M101A3/A2 bed sit directly on top of the truck frame just like the factory truck bed. Out back we added some more 2-inch square tubing bed spacers and a 34-inch-long, 2-inch square tubing crossmember to allow the bed to sit level. Another four 5x1/2-inch bolts keep the back of the bed in place.
