Pro Stock Spoiler Pics

I would like to put a custom pro stock style spoiler on my 1971 Demon 440. It's basically for show since there is no local track here. I like duck-tail spoiler but they are few and hard to find. I have seen them in 10" widths but I don't want the supports attached to the bumpers. It will attached to a bolt on fiberglass deck-lid. Any information and ideas or shops that deal in these spoiler would be AWEsome!!! Have a great week-end.
