Same here (gee, sounds like a group buy). I even have an ad out to buy from anyone replacing theirs with a painted one...none so far.
It bugged me everytime I saw it, so until then, regrettably I made a bandaid...I cut out a piece of 1/8" black plastic (sintra) 3"x12", angled the sides to match the grill & taped it to the bumper.
It covers the 3" dimple & at least from a distance it looks like a vent or a license plate holder...sorry, too embarrasing for a pic. So please someone find bumpers cheap so I can take it off!
