Do you have a picture of what you did? How do you mount the ABS sheet into the bumper? My fog lights are not in greatest shape. Leaving it off with empty hole is not an option - wife do not approve.
I traced the shape of my fog light (lens down), including the mounting tab toward the outise of the bumper. This way they mount exactly like the fog lights would. I simply used a little bolt and nut (head painted black) to keep it all in there snug as if it were OEM. With projectors, my fogs were completely useless, so I'm not missing them at all.
