Buy a el cheapo plasitc one and take it to your local machine shop and tell them to make you one. Get ready to pay out your ass tho. Last year, I made one like that for one of my friends and his explorer. It was aluminum. I annodized it red and then swirl brushed it to bring the swirls back to the normal aluminum color. If i can get him to send me pics, ill post them, it looks pretty sweet.
EDIT: This was when I had the schools machine shop and plating labs available at my disposal
