If the truck did not have a bed, it don't need one to be driven, but it will need Tail/turn/stop lights, and mud flaps.
A 1 ton would not have a bed, and a pickup bed in most cases will be too short of too long depending on the wheelbase on the truck, a long bed pickup is 127" (8' box), one tons came in 121", 133" & 157". They did make a 1 ton step side pickup on the 133" wheelbase, it had a 9' box and single tires on the rear.
$500 was a vary good deal...
