Look at the title: the name of the manufacturer. Finishline, and no doubt other sellers of Cobra replica parts. sells a "manufacturer's serial number plate." The buyer can then fill in the serial number himself. Go to
www.csx427sc.citymax.com. There are a lot of photos of original Cobras. Many 2000 and 3000 series cars start of with a photo of the serial number plate. Compare very closely your photo with those on the website. I think all of the serial numbers of the Shelby 2000 and 3000 series cars were etched by hand: not stamped.
