im pretty sure the spline count depends on the year the tranny is
Count the splines.

You should be able to use a 12 bolt. Check your spline count. Standard spline count is 30, you can change the axles to a 35 spline and gain as much as 89% strength. There are many vendors to help you with ordering the right parts. Let them know your use and horse power.
Type your answer here... you will need to take the yoke off the front diff. and count the teeth on it. if it has 28 teeth its a 28 spline or if it has 30 teeth its a 30 spline
count your teeth on your ring gear <big gear> and on you pinion <little gear> and the divide the ring gear teeth by the pinion
To determine your diff ratio, remove the cover, count the teeth on the ring gear, then count the teeth on the pinion gear. Divide the ring gear number by the pinion number.
There are four ways to find a ratio. 1 A dealer can normally tell from the vin number. 2 There are normally tags or labels on the axle that have part number, gear ratio, and fluid requirement info. 3 You can count how many times you have to turn the driveshaft to get one complete turn of the tires. 4 You can divide the number of teeth on the ring gear and divide by number of teeth on the pinion.

Take the rear end plate off and count the pinion gear teeth, write it down. Now count the ring gear teeth, write it down. Then divide the pinion # into the ring gear # and that will be the gear ratio.
The best way is to count the teeth on the ring gear and divide by the number of teeth on the pinion gear. Or you can count the number of turns of the pinion it takes to get one full turn of the ring gear. For example, if we divide a ring gear with 41 teeth by a pinion gear with 10 teeth we find that the gear ratio is 4.10:1 (41/10 = 4.10).
