Truck Preparation
1. Check part quantities using the Parts List on Page 2.
2. Block vehicle wheels. Some vehicles may require you to raise the rear of the truck in order to make it easier to drill for installing the mounting brackets on the truck frame.
3. You may wish to remove the wheels to give yourself greater working room.
4. If you have purchased a template, proceed to the “Template Method” below; otherwise, begin with the “Layout Method.”

Marking Bed for Drilling
Layout Method
1. See “Truck Bed Dimension Table” under “Layout Method” on Page 4 for the dimensions. Measure and mark from the back of the bed forward, the values for “A” and “B”. Do this at any point on both sides of the bed.
2. Draw a line across the bed from mark to mark.
3. Find the centerline of the bed.
4. Draw a line down the middle of the bed from front-to-rear.
5. Center the measurement of “C” across the centerline at the front-most line you made in step 2 and mark the measurement on each side (parallel to the centerline).
6. Center the measurement of “D” for the rear most line made in step 2, and again mark the measurement on each side (parallel to the centerline). This will locate the 4 drill holes.

Template Method
1. Lay the template in the truck bed, centering it from side-to-side, and parallel to the end of the truck bed using the dimension “X” listed in “Truck Bed Dimension Table” on Page 4.
2. Mark the 4 holes, while making sure the template does not move.

Mounting Bracket Installation
Part 1: Bracket Placement & Bed Hole Locations
Since most truck beds are not installed square to the frame or are the same distance from the back of the cab, the installer will need to make sure the bed holes line up properly with the center of each mounting post hole.
The basic steps in this section are as follows:
• Layout the bed holes
• Drill the first pilot hole in the bed
• Check centering using the tape method
• Adjust the bed hole layout if necessary
• Drill the second pilot hole and check centering to ensure bed hole locations are square to the frame; adjust as needed
• Drill remaining pilot holes in the bed; check centering
• Drill truck frame, if needed
