There was a tag on the diff as well. However, if you jack the rear up and spin the tires you can count rotations. Mark the tire and the drive shaft, count howmany times the driveshaft rotates for a full rotation of the tire. Normal ratios are 3.73 or 4.10, so either the DS will spin just short of 4 times or 36 degrees more than 4 times.
