pull the cover

count teeth and divide them

3/4 tons never came with 10 bolts from the factory. either it's not a 3/4 ton, it's a not a ten bolt or your axle has been swapped.

jack up one rear tire, spin it around twice. count how many times the driveshaft turns. that's your ratio.

not realy.

first look for a ratio tag on the bolts for the cover, its about 1"x1.5", it will have the teeth count and ratio. do the same for the front cause the axles probaly match.

or pull the cover of and count the teeth around the ring and then pull the pinion and count those teeth, divide ring teeth x pinion teeth = ratio

there are only a few rations avalible

3.54
3.73
4.10
4.56
maybe 4.88
5.13
maybe 5.38

it will be very obvius if you have 4.10 or ### higher you wont go very fast but the truck will jump on it.
