For checking your rear gear ratio, if its a positraction, turn the tire 1 full revolution and count the drive shaft turns.
For a non posi, lift only 1 tire and rotate it 2 complete turns and count the drive shaft revolutions.
I'm assuming this is a 4x4?
If so, you will need a Stewart Warner adapter box built. They dont make a wide varity of gears for the transfercase.
