Years ago I had a '64 Landau (sp). I was told then, that the T-Bird vinyl was patterned off of the texture used for the tops used on Model T closed cars. If you are having trouble finding the vinyl, you might want to source it through a Model T parts supplier. I'm sure that black was the only color used, but maybe they can connect you with the manufacturer, and you can ask them. In the Chicago area, there's an upholstery shop called Riggs Bros. They've been around for over 75 years and are famous for doing good work. There's more than one location now...I know there's one in St Charles. Call them. I bet they know what you're after, and could probably send you a sample of the material.
