I have a 93 Indy Pace Truck, and the front bumper is the same style used on diesels, with no impact strip and 2 large openings on each side of the front plate bracket. Inside these openings are plastic close-off panels, and they sort of snap together from what i can tell. I am missing one the goes inside the rectangular opening on the drivers side of the license plate, inside the bumper. Is there anywhere i can get one of these aside from finding a diesel truck in a junkyard somewhere that may still have it in place?
