Don't mean to hijack this thread but it's old (like me). While removing the undercoat off the firewall of my 69 Barracuda, I found this marking under the original paint. It's not a number like the similar photo in this thread. It's hard to tell in the picture but I can see the tracing under the paint and it's an SS. Not sure what that means. Maybe the initials of the guy who inspected the body prior to paint?
