    4.10. the "10 41" gives it away. 10 teeth on the pinion, and 41 on the ring gear.

    4.10

    The 10 is the pinion gear teeth, the 41 is the ring gear teeth. Divide 41 by 10. I *think* the 2 and 74 are the date code, and 3977334 is the part number.

    If I remember right, the 3.73 gears are 11 and 41, and the 4.56 are 9 and 41.
