6. Position Bumper in place and start bottom bolts using (2) 7/16"-14 x 1 1/4" Hex Head Bolts or (2) M12 x 35mm Hex
Head Bolts (depends on the year model), (2) 7/16" Flat Washers, and (2) 7/16" Lock Washers. Do not tighten at

7. 97 TJ's have holes on the inside of the frame rail. These holes are not on 98-on TJ's and are not required. These
are optional and will require dropping the fuel tank to reach the installation of the inner Metal Plates. However if
you would like to install the inner Metal Plates, they must be drilled to 7/16".NOTE: Measure the distance on the
mounting bracket and match these measurements on the frame or you may mount the outer four holes to the
frame and use the holes on the bracket as a template to mark the drilling locations (Figure 5). Remove Bumper
and set aside. Drill the frame holes to 7/16". CAUTION: Use extreme care in assuring the locations you drill
are correct. Before drilling be sure to check the backside of the frame for possible hazards or
obstructions.
