Ring gear id numbers

[CrewCab59]

Are the numbers stamped in the ring gear tell what they are for and size?

Thanks

First group of numbers is a part number of some sort, next group of numbers is the number of pinion teeth followed by the number of ring gear teeth, last group of numbers is the build date.

example... GMxxxxxxx 11 41 12 83

This example would be 3.73 gears (11/41) built in December 1983
