1. Prepare the Guide Plates and Anchor Plates for installation by using the adhesive strips
provided to attach the black plastic spacers to the Guide Plate and Anchor Plate as shown in
Fig. 1 & 2.
2. Position the silver Guide Plate such
that holes marked "3" are toward bed
side wall, the top edge is 11
1
/2 inches
down from the top of the bed rail, and
the outside edge is 1/8" in from corner.
(Fig. 3 & 4) Set plate parallel to bed
floor and secure in place with masking
tape.
3. Drill
1
/16" pilot holes in bed front
wall through the two small holes in
guide plate. If a stabilizer bar (SB-100)
is being installed (recommended),
Remove Guide Plates and attach stabil-
izer bar per instructions enclosed with bar. If no stabilizer bar is used, insert and tighten the
small sheet metal screws to secure Guide Plates to bed, then remove tape. Otherwise, do this
after the bar is attached.
4. Once both Guide Plates are attached to the bed with the small sheet metal screws, use the
Guide Plates as drill guides and drill
7
/16” holes through the bed front wall through hole pairs
marked 1 & 3. (Fig. 4) Caution, do not allow drill bit to strike cab. Place a board
or some other barrier between bed and cab while drilling.

5. Slip the black Anchor Plates (with spacers attached)
between the bed & cab and start all four 1" X 3/8" bolts
through Guide Plate and bed, into threaded holes in Black
Anchor Plate. Important: Start all 4 before tightening.
( Hint: These will start much easier if you run the bolts
through the plate prior to installation to clear the paint
from the holes.)
6. Once all 4 bolts are started, remove the sheet metal
screws, then tighten all bolts just until all parts draw
snuggly together.
IMPORTANT NOTE: This plate will roughly follow the contour of the bed front. Since
this is a "universal" plate, designed to fit a range of trucks, it will not follow the contour
perfectly, however, all parts will draw together when tightened down.
See reverse side for rear anchor installation.
