1. Remove and discard the 12 mm diameter bolts at end of
frame. Some vehicles have 8 mm diameter bolt on passen-
ger’s side. Remove that bolt and reinstall it with the head
on bottom of frame.
2. If your vehicle has rivets on bottom of frame, you will
need to install one 3/8" thick spacer between frame and
bracket at each bolting location.
Do not bolt brackets
directly against rivets.
3. Using supplied 12 mm screws, 1/2" flat washers and lock
washers, fasten brackets to frame where the 12 mm factory
bolts were removed. See diagram. For short beds use hole 2.
For long beds use hole 1.
NOTE: Some dual pipe exhaust
systems will hit the bracket. Exhaust will need to be
modified.
4. Short beds. Insert 1/2" screws with l/4" plates down
through 1" diameter holes in frame and into holes (4) in
bracket. Install 1/2" washers and lock nuts on each screw.
Leave nuts loose at this time.
5. Long beds. Insert 1/2" screws with l/4" plates down
through 1" diameter holes in frame and into holes (3) in
bracket. (On some models the forward holes may be 1/2".)
Install 1/2" washers and lock nuts on each screw. Leave
nuts loose at this time.
6. Place middle section between brackets as shown. Spare
tire may need to be loosened. Attach middle section using
3/8" screws, washers and lock nuts.
NOTE: Be sure to use
four holes to bolt side brackets to middle section.
7. Tighten nuts in the following order: First torque 3/8" nuts
to 40 ft-lb. Then torque 1/2" nuts to 70 ft-lb.
8. Retighten spare tire if it was loosened.
9. Be sure that spare tire is not rubbing against brake hose.
If needed, bend the brake hose bracket so that you have
clearance between tire and brake hose.
10. Install plastic plugs into 3/8" holes in middle section.
