1968 #3210 was destroyed. So, you can stop looking for that one.
Just so you know, the Shelby American Automobile Club has information on hundreds of cars that are not in the Registry. It has been my experience, they reserve the right to withhold that information for various reasons and to people that can't prove ownership. Sometimes it is by the current owner's request, other times it's because the information could be useful to someone up to devious deeds.
I am not saying that's the case here, but just because you can't find anything in the Registry or through a couple of inquiries on the internet, doesn't really mean a whole lot. Kind of curious you have a history of looking for cars not listed in the Registry. It maybe helpful to explain more in the future why you are trying to find all of these cars.
