I mounted mine inside the grill, the top grill. I drilled holes on bumper and had to rig up some extra pieces of metal to mount it farther back in order to clear. I think mine is a 23-24 inch. I'll try to take some pics after work.
I am looking for the one that fits in the bumper, not the grille. Maybe this one... https://www.rigidindustries.com/mounting-options/46581
Do you have to cut the plastic in the bumper slot, or does that simply remove?
