Dave, I think they call it a "front bumper reinforcement", whatever that is. The part is so thin I really hope it's not reinforcing something important. If you figure out where it goes, and you need a new one, you can have the one I have because it's not doing me any good.
"The major difference between a thing that might go wrong and a thing that cannot possibly go wrong is that when a thing that cannot possibly go wrong goes wrong, it usually turns out to be impossible to get at or repair."
