great idea. did you forego the middle bolt or affix it to the bolt somehow?
Those three bolts attach the stock fender support to the grille. Since the fenders are cut and that support is gone none of them are really needed (as far as I know), so we just drilled it out to 3/4” to fit the side marker.
P.s. Kicker self-powered sub installed this morning in the white Jeep! Plug and play with no issues!
