Ford kept track of the various parts and castings in its inventory by assigning each item its own unique alphanumeric identification number. These numbers provide a lot of information to those who are familiar with what the numbers mean. The unique identifier is a series of numbers and letters that are put in a specific sequence, and the location of the digit determines what that digit designates. Information commonly provided by part numbers includes the decade during which the part was designed or manufactured, the year of the decade the part was designed or manufactured, the car line the part was originally designed for, the engineering department originally responsible for the design, the basic part number, and the changes made to the original design.

C4 Case Numbers

What can be confusing about these numbers is that a part designed for one year might actually be used for several years, or a part designed for one car line might be used on other lines as well. For instance, a part originally designed for a 1964 Ford could often be found on a 1964 or 1965 model Thunderbird, Mercury, or Lincoln as well. It is actually quite common to find parts originally designed for Thunderbirds on Lincolns, and Falcon parts on Mustangs. In order to spread out the costs of designing and manufacturing a part, Ford used parts on different models.
