Ford cars and trucks from 1968 on have an axle code on the Certification Plate, information on this plate can be used to determine if you vehicle is factory equipped with a limited slip positraction rear end - differential. The certification plate can be located on the lock face of the left door edge. The plate layouts vary depending on the model year, but in every case the axle code section is clearly marked as either "axle" or "ax".

 

The following figure presents differential cover/cover gasket shapes. Counting cover bolts and cover shapes is a common method to determine which ring gear diameter differential you have in your rear wheel drive vehicles
