It doesn’t take a Jay Leno to recognize that the Shelby GT350 and GT350R will be (if they aren’t already) classics. As a result of their ridiculous performance and natural coolness, though, copycats are sure to start cropping up.

Now, you can get your 2015-2016 Shelby GT350 and GT350Rs certified as official.

The Ford Performance Info Center has expanded its Certificate of Authenticity program to include those Shelbys.

You can order a Ford Performance Certificate of Authenticity Package for your Shelby that includes an official certificate of authenticity, a VIN decoder, production summary chart, poster, tri-fold brochure, certificate sleeve, track tips, window sticker, “Disc Brake Rotor & Caliper” business card holder, and a cobra keychain.

Unfortunately, though, these will only be available for a limited time so you’d better get cracking if you’re interested. Go to Ford Performance Info Center’s website to find out more.
