Starting in mid-80s, Axle Code is on door-jamb sticker.

Counting

To verify the ratio in the vehicle matches the original equipment (or build tag), you may count turns of the wheel vs turns of the driveshaft. If slightly less than 4 turns of the driveshaft results in one turn of the wheels, it is a 3.9 ratio. If it takes a bit more than 4 turns, it is a 4.111 ratio.

Even better is to note the stamped numbers on the ring gear. For example, this unit is stamped 39:11
24439.jpg
39 divided by 11 = 3.545 ratio

Pinion gear is similarly stamped
