Blackford03

Hi all, really hoping for some help here. I purchased some square style smoked fog lights for my 05 FX4 and am having huge trouble getting the fog light off of the housing that bolts to the bumper. The 2 nutted bolts that attach the fog light housing to the bumper bracket are just spinning... I can cut them off, nut not sure how the new ones go on(no instructions)... Anyone seen any illustrations on this or anything to help?

Thanks!
