I can see the confusion, I cut some squares out of a foam sleeping pad and siliconed them in the ends of the tube just to keep water out. Because I didn't want to mess with the bull bar, I just used the 4 existing holes where the tow hooks are mounted and drilled the mounting plate to match. Those are the only 4 mounting bolts. If I didn't have the bull bar, I think I could have moved the mounting channel further twords the front of the truck. This would have eliminated the need for the 1" spacers. The bottom of the fairlead would have been hanging over the front of the bumper. If you need more pics, let me know.
