Re: Differential Question
Open diff (not posi) there will be numbers on the edge of the ring gear (big one), divide the second number by the first. Example. 11:41. 41/11=3.73 gears

Re: Differential Question
The edge where the green spot is in the first picture is where you'll find the stamped numbers.
