2 ways..

1) check the RPO #'s in the glove box.

2) put the car in the air in neutral, While spinning the driveshaft count how many turns the drive shaft makes to rotate the wheel one complete revolution

Also, unless it has been removed there is a tag on the differential with the ratio.

Good luck,
