hey guys, this is my first time on the forum. I searched for awhile but could only find 4wd removal. My question is what is the best way to remove the mounting bolts for the rack? And does anyone know what size the nut is? I pretty much figured i would have to hold a wrench on it to get the bolts out. My problem is I even hit them with a impact and they still dont move. Any suggestions on getting them out?
