reading a ring gear

[grapehead]

its been awhile since ive last done this so forgive my n00bishness.

i got a 10 bolt front. the last bit of the ring gear stamp reads "11 41 12 85"

is this a 3.73 front made in dec '85, or a 3.42 made in 85?

thx

Should be 3.73

*usually* the first number is pinion teeth, and the second is ring gear teeth.. 3.727272727272727272727, or 3.73 in this case..
