I don't think there's any harm in adding one hole per horn,.... once the bumper is mounted with the end horn bolt, and the slotted side bolts, there is an extra hole on the frame mounts of the bumper that isn't slotted....drilling a hole through the frame, through those holes, would lock the mount so it would not pivot.

I believe that was always an optional mounting point, so Jim already has given the option if desired.

I'm not sure if the frame mounts on every year's bumper have those extra mounting holes or not, but, if you have them, seems to be an easy add-on...and, if not, you could always just drill through the bumper and the frame, and then slide a bolt all the way across.

I haven't done this, but then again, I like torque wrenches, and I appreciate the concept that if you torque something past the strength of the thread system, it can strip/be weaker than if you were more gentle....more isn't always better.



I also like lock-tite, etc....so my shit don't fall off.
