I dont know about counting the teeth but there should be a tag on your differential cover as well as an axle code on your door jam sticker. if both show up to be the same its 99% that you have the ratio it represented by the diff tag and axle code. if you use your axles from the 98, a 2000.5+ will, im pretty sure, require different axles
