1938 - 41 Ford Truck Bedwood Adapter
This is the basic adapter kit that was designed to convert the original sheet metal floor to the newer board and strip concept used later by Ford. There was not a front crossmember on the 38-41 bed boxes . Ford utilized two maple wood risers. They kept the front and rear of the bed level with the middle crossmembers that sat on the frame.
