on my 2005 sc430, REAR BUMPER, there was a separate piece approx. 3" x 8" that snapped into the bumper, thus making the rear bumper ''whole" with no holes, except for the 2 screw holes for the license plate. without this component, there is an opening in the bumper which reveals the foam core, etc. on the bumper itself. does any one else also have this component on the bumper? if so, can you help me with a photo of your rear bumper showing the bumper to be one whole piece with just the two screw holes for the license plate. please help! thanks so much!!!!
