Vin Decoder for Classic Mustangs - The Key to Finding the Correct Mustang Parts9484388

You have decided to restore your classic Mustang, or research one to restore, but how do you find out what Mustang parts your particular pony car rolled off the line with? Knowing the vehicle identification number - the VIN will guide you in discovering what was installed on your Mustang when it was brand new. Since we are only talking about restoring a classic Mustang, these codes will only cover what are considered the first generation Mustangs, 1965-1973.

Finding the VIN plate is the first step. The first two year models have the VIN under the hood on the 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. Another thing to look for is the data plate that may be riveted to the jamb of the driver side door. Note that you may not find the original data plate, reasons for this could include cases where the door has been previously swapped out, the plate was removed or lost over the years.

The VIN decode follows a basic standard. 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. Each model year has some variation on the Mustang parts; the model years are decoded below.

The data plate holds a plethora of information. If you can find the original one for your Mustang you can determine the original color, trim style, the date it was manufactured, District Sales Office number, rear axle identification, and transmission. If the data plate VIN info is different than the VIN plate on the fender or windshield, you'll need to investigate further. Search online for Mustang VIN  and data plate decoders to help you decipher the information for your classic Mustang.
