I just aquired a calmini winch bumper for my 03 Frontier (I know, its not a cool as an Xterra but close enough ) and I can't figure out how to mount the skid plate. What do the rear bolt connect to? Is it like the Skid Row plates and require a second skid plate to work? I could not find any place to mount it, so I figure I am missing some piece or I am an idiot. Which is it?
