The Cobra name has been tied to the Mustang for quite a while. In 1979, 1980, and 1981 Ford had a Cobra package they put on the Mustang GT. From 1983-1991 Canadian cars that were Mustang GT's here in the U.S. were labeled as Cobras across the border. Whatever application you are looking for, Late Model Restoration has the Mustang Cobra Exterior Decals you're looking for to fit your application.
As a deployed service member, there are not many avenues of contacting companies back home conveniently. Between the time difference and use of wifi or morale phones, it can be challenging. Luckily the team at LateModel Restoration emailed me back quickly and gave me everything that I needed for a smoothe purchase, and a few more that followed. They were quick in reply and quick to help me out and I have my parts on the way to my home now because of it. I will be shopping here primarily and I recommend it highly to fellow Mustang folks.
