Two differential carriers were used in these axles with the exception of the 2.24:1 ratio. Any other ratios between 2.45:1 and 2.71:1 used one carrier, while anything above 2.71:1 used a larger carrier. The ring-and-pinion assemblies are accessed from a rear cover that is about 11-1/4 inches across by 10-1/4 inches high and has an oval 10-bolt pattern.
