markings on a ring gear

[rr41mag]

SO i decided to fix my rear end leak. "15 41 001 307" Was stamped on my ring gear. The housing has "AA" stamped on it. What does this mean?

I suspect the 15 41 is they are 2.73 gears.

The other may be a date code.

The diff brg caps should have stamps to match them to the side. See if AA is on one of the caps. Should be same side as the housing.

And I'm running 35" tires. No wonder it's kinda tuff taking off at a red light

This helps with the stampings on the outside of the differential
Jeep Axle: AMC 20
-appears to validate the 15 and 41 giving you the 2.73 ratio
