1978 Rear axle

RE: 1978 Rear axle
From the Mustang II web page >> Mustang II Axle Identification
The Mustang II utilizes two different style rear axles. The first axle is used on 4cyl and some 6cyl cars and is a 6 3/4" ring gear integral carrier axle. The second is used on some 6cyl and all 8cyl cars and is an 8" ring gear removable carrier axle.
The two axles are easy to tell apart. Looking at the axle from the rear of the car, if the center section has a cover with bolts around the circumference, it is the 6 3/4" axle. If there are no visible bolts from the rear, it is an 8" axle.
The following descriptions are from the Ford Shop Manuals. I have left the 9" references intact since this is a popular swap for cars that have severely modified engines with much more power than the stock engines.
The following axle identification is based on the axle tag located on the axle, if you have the code from the door tag (Certification label) you can look up your axle in our code reference section.
