Yes they are still using clay! I tried to research first gen Mustang clays but for '65-'66 there's a problem besetting researchers--they weren't called Mustangs so what name they are filed under is anyone's guess(the example i show is labeled Torino) Others have a cougar in the grille so that was a strong favorite until near introduction. One funny one I found looked like the '64 Ford GT with a pointed nose, hidden headlamps. That goes back to '62, before there was a GT40! There's also Mustang four doors, wagons, etc, but I only care about ones that were proposed for Shelby. We can talk price depending in the quality of what you have, or talk about trading for fine art prints (pictures of art available, write malibucarart@gmail.com)
