Stamped into the ring gear are the number of teeth on both the pinion and the ring gear. Divide the bigger number by the smaller one. This one is marked 15 , 41 = 2.73
I would guess If you have a 3:73, You would have somewhere around 41 teeth on the ring and 11 on the pinion.

Or you can count them. Either way.

Hey, You looking for 41 and 11. 41 divided 11 = 3.727 or 3.73

turn the brake drums (if it's a posi both should turn at same time) 1 rotation and count how many turns the yolk makes.
