These are two of the three 1965 Mustang Shelby GT-350 prototypes. The front one is a street version - serial number SFM5S003. The other is one of two race prototype versions (SFM5R003 GT-350R Prototype). These started as white K-code (HiPo 271ho 289ci) 1965 Mustang fastbacks. Where is the third one? It exists and is in a private collection.
