FAB Quest Automotive Calculators and Charts: Axle Identification Chart by Cover or 3rd Member Bolt Configuration.

Please note that the Ford 8 Inch and 9 Inch images are of the 3rd member or carrier where it bolts to the front (engine facing side) of the axle since neither of these differentials have a removable access cover. If you do not see your axle listed, please e-mail us and we will assist in identifying your axle!
