Re: ID help on GM gears
Heavy duty 4.88 gears. May or maybe not matched. Some times there can be quite a spread, but mine were only about a week apart. Maybe someone else has had more experience.

Page 5 The HD 4.88 gears were over the counter only (3916232-3916233)as part 3917972. The dates look fine to me based on the ones that I have seen. Hope this helps.
