Just wondering if someone can tell me how or what is the easiest way to find out what rear ends i got in my 94 gc want to purchase lockers but not sure what to get or gear ratio any help would be great Thanks

 

With out sounding like a Jerk, the easiest way is go out to your Jeep, lay on your back, read the tag on the Axle itself.

Or take your VIN to the local jeep dealership, ask for a build sheet and it will be listed on it. Cost me a smile and some time while he printed it.
