- 1). Cut the uprights for the rack from 3/4 inch exterior grade plywood. These uprights are in a triangular shape with the long side the length of the height of the cab above the rails of the box. Cut the bottom of the triangular support about 9 inches long. The top of the support is 4 inches wide with a straight line connecting one end of the top to the same end of the bottom and an angled cut between the other end of the top to the other end of the bottom. Cut 8 identical pieces.
- 2). Cut two 2- by 4-inch boards to the width of the truck box. These serve as the platforms where items will ride above the cab level of the truck.
- 3). Assemble the upright supports. Place a 2-inch wide wood piece between two of the upright supports at the bottom to serve as a foot for the upright to rest on. Use 2-inch galvanized deck screws with three placed into the foot board from each side. Place a similar 2-wide piece between the top of the plywood supports. Use 1/4-inch carriage bolts to fasten the top block between the uprights. Create four of the upright assemblies.
- 4). Attach the top crossbars between two of the upright assemblies. Use two 1/4 carriage bolts at each support to fasten the crossbars to the block between the two sections of the upright assembly. Create two of these rack assemblies.
- 5). Attach one rack assembly to the rails of the box of the pickup immediately behind the cab. Fasten the assembly to the rail using clamps for temporary use of drill holes through the foot block and the rail of the truck box and fasten in place with 1/4-inch carriage bolts. Fasten the other rack assembly to the rear of the truck box in a similar manner.
