Okay,

I took the back cover off of the now sold 12 Bolt rear I have. I am going to count the teeth on the ring and pinion and do the math however I found the following info on the ring gear:

E4H
1 GM 3853010 11 39 3 67

I am guessing this translates to a 3.55 posi that was made in 3/67

Am I right or do I still need to count the teeth?

Thanks!

39 ring gear teeth and 11 pinion teeth. 3.55 I'll never figure out why people want to count the teeth when GM does it for you.
