The Ford part number on the box shown at left is on the top line: B8A-9431-A. In order to spread out the costs of designing and manufacturing a part, Ford used parts on different models. It is actually quite common to find parts originally designed for Thunderbirds on Lincolns, and Falcon parts on Mustangs. 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. 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. 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.
