Well, even though, they did not put the P-51, one of if not the greatest prop driven planes, in their emblem but stuck with the pony.
They went on to model varients of Mach 1, Boss, Shelby, Cobra, GT, Anniversary models, SVO, Bullitt, Grande and Ghia.
Roush, Hurst, Saleen, ect were made by separate companies and Shelby was the only factory calaboration.
