    These are the numbers on my ring gear. 344161 12-41 GMK I think the 12-41 means 3.42 gear ratio, but what do the other numbers mean? I googeled the 344161 ring gear and it said it was from the H body Chevy. Monza??? I couldn't find GMK anywhere. This is suppose to be an S-10 rear end.

    Help me out fellas.

    Thanks

    The 344161 is the GM part # and the 12-41 is the tooth count on the gears. 12 on the pinion and 41 on the ring which gives you a 3:42 ratio just as you said.
