All I saw for sale where fiberglass or plastic ones. I suppose you could cut the center of your front valance and fold the bottom section and sides inward but you will need something to join the corners so a little welding would need to be done. I remember somebody on here having done one recently as a means of getting more air to the radiator. I even thought just removing the area where a license plate would go would improve airflow or would be a great place to mount a trans, oil, or even power steering cooler if it didn't reduce flow or transfer heat to the main radiator. When you wanted, you could even put a license plate over it to cover it up.
