Z= 3.08 axle ratio,Traction-lok differential...thats what the factory installed in the 95's with the Z code...thats not to say yours has not been changed...
I usually do jack the car up and turn the tire and count the driveshaft revolutions. I have not had time to do this yet. The car is totally stock, except for some flowmasters. I am looking for some tips on free mods.
look on the diff cover for a tag
it should look like
2 L 73= 2.73
3 L 08= 3.08
3 L 27= 3.27
if you plan on changing the fluid then take the cover off then count the gears, but its easier to count the DS vs. tire rotation just incase someone changed the gears,
its most likely 2.73 most cars got this gear set, but i really dont know the car
