I'm looking at a 68 GT350 project. The fender VIN tag has two numbers on it, the correct Shelby style VIN, just the VIN no -xxxxx after it. It is stamped above the box where I have seen most (not many, no expert) so it sits below the snake emblem and above the box is stamped over the text "Vehicle Serial Number".
There is a second longer 14 character number (alphanumeric) stamped in the box.
The font and reverese stamping looks like others I have seen.
Red flag???
