12 bolts 3.42 ratio.Number of theets?

[COKE]

I have a 12 bolts from a 79 Jimmy.
It is a 3.42 ratio,the pinion and the ring has stamped the 34:10 digits.

Should it to be 41:12 or did they change the number of theets in any year?

Thanks.

do you have a front and rear end, or 2 rear ends? no such thing as a 12 bolt front. did you count the teeth?

 

[COKE]

I have both axles from a 79 jimmy (Front 10bolts and rear 12 bolts),and i only have removed the cover of the 12 bolts(Rear).

It has the digits 34 and 10 stamped in the ring and it also has them in the pinion surface.

My doubt is because all the GM 3.42 ring and pinios kits that i have seen were 41:12.

either way, it's the same, nothing to worry about.

Yes,it is the same ,more or less(It would be 3.40 instead of 3.42),but it is rare because i only have seen this proportion of ring and pinion theets in the Ford axles.

I am willing to bet it's "teeth". English is hard.
