Default Alternator and differential date codes

Sorry to bother everyone with date codes but looking over some pieces and I'm not sure what year their from. Differential really because I need to know what gears are in there.

Alternator:
1100710-55A
6C22-12VNEG

Differential
AWW 322 E1

Thanks everyone!

Hi Pm,
The alternator would be 6 for the year, C for March, and 22 for the day.
The differential would be AW for 3.08, W for the plant (Warren Motive), 322 for the Julian date, E for posi-traction source (Eaton), 1 for shift. (Thats what it was originally…. not necessarily what's in there now.)
Regards,
Alan

Thanks Alan. Yeah from what I've looked up online I figured it was a 6, just want sure 66, 76 etc? Guess there's no way to pinpoint decade. In a 69 so I wouldn't figure they would have a 66 lying around the factory that they used!

Hi Pm,
Looking at when the part number was being used in production will often clarify the decade.
