Key – This is not intended to be a definitive list for your vehicle as there are many online decoders which will do that job for you and give you a more acurate decode. Each model year has some variation on the Mustang parts the model years are decoded below. From left to right the first digit is the last digit of the model year, the code for the assembly plant (1 digit), body style (2 digits), engine code (1 digit), followed by the consecutive unit number. If you have a matching numbers car then you have a rare beast indeed and increases the value significantly. When all the VIN numbers, and door tags match up with the engine block and transmission numbers this is what is known as the “Matching Numbers” car.

This was a feature to stop the VIN numbers being ground of and re-stamped if stolen for example. There is also the “secret” VIN number which is actually hidden under the right hand fender towards the cowl area, again on the inner fender.

The 1964 1/2 – 1966 models had their VIN numbers stamped under the hood on the inner fenders edge of the driver side fender, 1968 models display the VIN at the base of the front windshield where it meets the dash on the passenger side while later models display the VIN on the driver side.
