This 1964.5 Mustang was produced July 17th of 1964. It was a Dearborn produced car that was sold new into California where it has spent its entire life. Though the serial number decodes as a 1965, these early cars are referred to as 1964 1/2’s by enthusiasts as they have many differences from the later 1965 models. July 31st is considered the end of production for cars that can be designated as 64 1/2’s so this car was near the end of that run (which started in March of 1964). Most differences are very subtle, while others are more obvious such as a generator instead of an alternator.
