Gentlemen, I've "steered away" from buying fog or driving lamps for my 77 B because I've never really understood how they could be mounted. Has anyone tried drilling into the underside of the big black rubber bumper? I imagine that once they're nicely mounted, the rest is no biggy, but would a typical power drill make its way through this thing or am I looking at renting a Bobcat with a bumper hitch auger attachement?
