Good morning,

There should be a tag on the differential. It is attached to one of the bolts that hold the cover to the housing.

If you give me the information off that tag, I can give you the ratio.

If the tag is not there. then jack up the car and on the back of one of the rear tires, use a crayon mark as a reference. Do the same to the driveshaft as well.

Then turn the wheel one complete revolution and count how many times the driveshaft turns. Tell me the result and I can help there as well.
