Jeff,
2+2=GT350 was kind enough to point me to this post about a dash/hyphen in a VIN. I posted pictures of my VINS on Vintage Mustangs Forum, titled VIN number with dash/hypen in it?, showing the hyphen where a 9 is supposed to be. I was hoping you could share the picture of the example you mention in your post above. Much appreciated!! Also by any chance do you know where I can find a picture of the stamping machine?
