Identifying the Differential on a Ford Falcon
To identify the differential on a Ford Falcon, you can follow these steps:
1. Check the Build Plate: You can begin by decoding the build plate on the door frame of your Ford Falcon. One of the codes will be under “ax”, which will indicate the axle that your car came from the factory with originally. Most ’63 Falcons came with either a 6.75″ or a 7.25″ rear end. Some 63 Falcons also came with the 7″ gear.
2. Visual Inspection: Each Ford model has a different number of bolts, and certain Dana units have the same bolt count. Ford 8 and 9-inch rear ends are removable carrier units and have no inspection cover. The back of these units have a smooth hump with no bolts. Comparing the bolt count and inspection cover gasket shape can also help in identification.
3. Differential Tags and Stampings: The most accurate differential identification is provided by the bottom line of the tag number or axle tube stamp. Differential tags can easily be used to identify Dana and Ford differentials. Ford differential tags are a bit more direct. The tag number is ordered as year, month, and day with the month of manufacture following the format of A for January, B for February, C for March, and so on. A Ford tag number will appear something like 12D04 which signifies April 4, 2012 .
4. Consult a Service Manual: If in doubt, consulting a Service Manual for a 1963 Falcon can also provide information on the rear end and help in identifying the differential.
These methods should help you in identifying the differential on your Ford Falcon. If you have the specific code from the build plate, feel free to share it for further assistance.
