Step 1
Locate the mounting tabs along the
bottom edge of the vehicle body.
For crew cab models, use the first,
second and fifth mounting locations.
For extended and double cab
models, use the first, second and
fourth mounting locations.
Step 2A
Starting on the front driver-side
mounting location, place a universal bracket
over the two factory mounting locations.
Attach the bracket to the body panel using
two M8 hex bolts, lock and flat washers.
Snug the hardware,
but do not fully tighten.

Attach the bracket to the
body panel using an M8 hex bolt,
lock washer and flat washer.
