I mean inside the frame fails. Not running plate inside the frame itself. There is thin metal welded on the rear caps of the frame rails that stock bumper is bolt through. Cut it out between frame rails. Used existing hole and metal outside frame rails to bolt to on top of the plate I am running 18" deep inside frame rails. Again pic to come soon and it'll make sense. But there is plenty of room behind the bumper for pin. Triple checked that and tailgate clearence.
