PREPARE THE CARGO BED
Attach the clamp bracket to the bulkhead, centered side to side
1
and flush with the top rail, using a drill, 3/8" nut driver bit, and four
self-drilling screws.
Installing the clamp bracket is easiest if you pre-drill it using
the screws.
Attach a lock-rod striker bracket to each front corner of the cargo
2
bed with its V bend rearward using a drill, 3/8" nut driver bit, two
self-drilling screws, and the two holes nearest the ends of the bracket.
Make sure the bracket's legs are located as high on the bed wall as
possible without them breaking the plane of the top of the bed rail.
It's OK for the top of the V bend
itself to break this plane.
Detach all three brackets by removing the self-drilling screws.
3
Use the holes in the truck
4
body left by the self-drilling
screws as pilot holes to drill
larger, 3/8" holes.

Hammer an aluminum rivet nut into each hole.

Do not install rivet nuts through plastic bed rail caps or plastic
bedliners. (Spray-on bedliners are fine.) Use a utility knife to trim
the plastic so that the rivet nuts' outer flange can sit tightly against
the body of the truck itself.
Insert the installation-tool mandrel into a rivet nut. Hand-tighten it
6
until its hexagonal sleeve is tight to the face of the rivet nut.
Use a 9/16" wrench to hold the sleeve as you
7
tighten the mandrel with a 7/16" socket until the
rivet nut deforms and locks against the interior of
the bed wall.
You'll know the rivet nut
is fully compressed
when you feel the
mandrel become very
difficult to turn.
Remove the installation tool by unscrewing the mandrel.
8
Repeat steps 6-8 for each rivet nut.
9
Reinstall all three brackets using the hex
10
bolts, plain washers, and a 7/16" socket.
Do not overtighten the bolts. If you
do, you might strip the rivet nuts.
If you are also installing a Cross Bin, do so now. Refer to page 2

of the Cross Bin Installation Guide for details.
