Chris the one in your link looks like mine but I think the ends are different. Mine looks like Tom's old spoiler but with the nascar angle like in your pic. I bought it from a friend for $50.00 but I haven't had it painted or installed yet. I am getting my roof, trunk, rear bumper, spoiler, and passenger ground effects painted very soon (like in March or April) and I'm having the trunk lock shaved, the ford emblem holes filled, and the spoiler put on. I work with a guy who used to be a body tech for years. Now he does it on the side and has a paint booth in his garage. He quoted me an unbelievable price. I'm sure he could do yours for you very reasonably. If you get a spolier that is not painted he can get the pearl paint and paint and install it for you. Email me and I'll talk to him at work about it for you.
And maybe today or tomorrow I'll go set my spoiler on the back of my SC and snap a pic.
