Yachtsmanbill, I hate to give away secrets, but I find most of my Model T cars and parts by driving a model T. For example, go to the grocery store or auto parts house with that model T. It opens up the conversation to old cars. That speedster in your profile might do it, but a T car would work better.
Currently there are two barn fresh cars I heard about in a local watering hole. By talking to fellow customers. I drive a T there when the weather is good. One is a 1930 Chevy 4 dr Landau which I have not found a price on yet and the other is a 26/27 T coupe which I will see shortly and maybe buy if the price is right. I almost forgot, I heard about two sedans while at a local church picnic with my T parked very near the picnic area. Church lets me park near as the old cars provide entertainment for the folks at the picnic.
