I'm thinking about fiberglass a bracket in the back. The lite covers are held in by snapping in to fascia.I think you would have to add brackets or something to mount the fog lights too in order for them to work.
Thanks for the input. I'm looking on flea bay for some small square lites the size of the opening and go that route. After I get the Smoothie bar and running boards from MPD than off to the painter.I went to Pep Boys and picked up a couple of nice lights and mounted them in the outside air vents. The lights are an oval shape and only about 2" wide by 1 1/2" tall. I used the mounting bracket that came with the lights but I had to make a spacer about 1/2" thick to get them down in the center of the opening. I mounted them at the very back of the air vent.
