if you take off the rear diff cover all you have to do is reinstall the cover and refill the diff. as long as you dont take anything inside the diff it'll be fine. there should be a ring/pinion number stamped in the ring gear, divide the pinion count into the ring gear count and it'll give you the gear ratio. it may have the ratio stamped right on it too. Also on the drivers side axle tube there is a 3 digit code stamped on the front side. Find that code and post it up, i have a list that beaks down what the diff is like posi or open, and gear ratio.
