Step 3: Proceed to drill the marked holes out to 3/8”. Be sure when drilling holes that you are drilling in
the center of the marked pinch weld area. (Usually about ½” – ¼” from the outside edge.) Doing
this will insure ease of installation of the nuts and washers.

Note: You will not normally be using the holes in the top of the mounting brackets. These
provide extra support if you plan on your bars impacting rocks or other hard surfaces.
These can be secured by using #8- 1inch self-tapping screws.(not provided) Make sure
no wires or other obstructions are in the way if used. Do not attach screws until bars is
securely fastened to the pinch weld area.
