FINAL STEPS: THE RULER
• Center ruler in embossed area and screw three 1/2" length Phillips screws through the tailgate side holes directly
into deck panels; BAG FINAL MID.
NOTE: These are small gauge screws. Light hand tighten ONLY.
• For the three cabside ruler mounting holes, drill each with a 9/64" bit and a drill stop set to 1/2". There is a
lateral steel tube that runs on the underside of the deck at this location. (SEE UNDERSIDE VIEW OF DECK).
IMPORTANT: Only drill through TOP of steel tube; do not drill through bottom of tube, otherwise you will
funnel water into your drawers; BAD!
• Screw three 3/4" length Phillips screws into the cabside ruler holes you just drilled; BAG FINAL MID.
STEEL TUBE RUNS LATERALLY UNDER THESE 3 RULER
HOLES. THEY TAKE THE 3/4" SCREWS.
DO: Drill through the top of steel
tube ONLY.
DO NOT: Drill through both sides
of steel tube.
