1. Use transparent tape to cover the mounting post hole on the top of each mounting bracket (when the pilot hole is drilled through the bed, the tape will be pierced by the small drill; it should be positioned in the center of the 1″ mounting post hole [see below]).
2. Remove the front two stock receiver bolts on the rear driver side stock receiver bracket (see illustration below).
3. Insert a wedge ( not included ) between the frame and the stock receiver bracket to create a gap for the mounting bracket frame plate to slide into place
4. Slide the rear driver side mounting bracket frame plate between the stock receiver bracket and the frame of the truck, aligning the holes in the mounting bracket frame plate with the existing holes in the frame.
5. Thread the stock receiver bolts through the stock receiver bracket, mounting bracket frame plate and frame.
6. Fasten the mounting bracket flush to the frame (some mounting brackets may have a slight warp due to the metal characteristics during the welding process) by using either a clamp or by inserting a fastener through the mounting bracket in the existing frame hole(s). Do not overtighten—you will be removing the mounting post holder in later steps.
7. Slide the mounting bracket post holder on top of the frame and bolt to the mounting bracket frame plate. Hand tighten only.
8. Repeat Steps 2-7 for the passenger side, rear mounting bracket.
9. Drill the first 1/16 ” pilot hole through the truck bed over the rear hole on the driver side where you made the mark during the “Marking Bed for Drilling” on page 3. The bit should come down through the 1″ mounting post hole, piercing the transparent tape, aiding the centering of the bracket front-to-rear and side-to-side.
10. If the pilot hole is off center to the 1″ mounting post hole, remember to adjust all the pilot hole locations accordingly.
