lol, they are from Simco LTD. Basically the company that makes the gauge clusters for Saleen, Roush, Autometer, etc.
I called them to see what they could do for me and they sent me the bezel (not the whole cluster) to use. Only problem is they don't want to sell them to the public like that. Check out their site. http://www.simcoltd.com/
I am the only person I know of using the bezel on stock gauges, because Simco only wants to sell their clusters, or sell custom clusters in larger quanities.
