I went to the Ford racing store here in Houston which is owned by Tommie Vaughn Ford, they just had one for sale. They are about $100ish and you should be able to pick one up (or order it) from any Ford Dealership that has a garage.
Cool thing is it's real easy to switch out too, just four plastic bolt/clip things and it comes right off. Just make sure you align the new one correctly or it'll look off center. Did that with mine and had to take it off and try again like a week later. :P

I've spent too long looking into the abyss. It's starting to look back.
