yes, the cobra does...but when referencing a "shelby", one is normally speaking of a shelby mustang. 
Unless they are talking about a Shelby Charger, or a Shelby Omni, or a Shelby Lancer...  Or maybe a GT40, or a Daytona Coupe, or a LeMans, or a Cobra, or a Viper....   
Seriously, Shelby has had a hand in so many cars, I can't believe people only associate him with Mustangs.
