If you jack the back wheels off the ground put it in neutral then turn the tire one rotation. Count the number of turns of drive shaft. Put a chalk line on driveshaft to make it easier to see rotation. It will probably be a little over 3 if its original. 3.08s thats my guess.If someone has changed them then the stamp #s will do no good. This will give You a very close estimate of what they are. Mine were originally 3.08 now 3.90.
