'06 Bumper grill replacement

I sold some camper stuff for a friend, and they have some receiver hitches behind their bumper grill. I was wondering where I could get a new grill to replace the cut one. I've got pics on my phone, but I can't upload them yet. I only have this one:

If anyone could give me some info on where to get one, I'd appreciate it.
