I stopped by a local garage today. They had a 1966 Mustang Convertible, C code Automatic. This thing was a grey color with a black top. The main reason I stopped was because I needed to measure how far back to place my side mirror. Well, the guy I talked to (I sort of know him) showed me a small Gold plate that he claimed to have found in the car, under the seat or dash or somthing, I can't remember. I saw the plate. It said somthing like "This vehicle was custom built for:" then in a scrip type writing it had a ladys name on it. He told me that he has seen a few of these, and it wasn't all that un-common. Whats the deal here? I have never heard nor seen one in my life. Is this a fake, or what?
