Inside of the vehicle (drivers side), remove the bolt that attaches the lower portion of the
seatbelt to the mounting post/pillar and discard it.
Outside of the vehicle, use the rear edge of the cab door opening to find the reinforcement
crossmember under the cab floor. Follow this crossmember inboard approximately 10 inches
and locate an existing 5/8-inch hole approximately 2 inches from the cab body mount.
From underneath the vehicle, using the existing 5/8-hch hole as a guide, drill a 1/2-inch
diameter hole straight up through the cab floor and floormat. This new attaching hole should
be approximately 6 inches straight back from the rear seat mounting bolt location.
If the floormat is still in the truck, cut and remove a 1 3/4-inch diameter section from the mat
around the drilled hole.
If the floormat and jute backing are wet, go to step 5; if not, go to step 6.
Remove floormat. When floor is dry, remove any rust with a wire brush and paint bare spots
with primer (NSN 8010-01-193-0517). Replace floormat.
From inside the vehicle cab, place one hex head grade 8 bolt (1/2inch 13 coarse thread x
3-1/2 inch long (NSN 5305-00-071-2077) through the mounting plate of the seatbelt. Plaoe
two 1/2-inch flatwashers (NSN 5310-00-809-5997) onto the bolt and install the bolt into the
drilled hole in the floor.
