1BLKJP I was under the impression that all 4 Cyl YJ's got 4.10's. 6 cylinder versions could have either 3.07, 3.54, or 3.73.

You can always be sure for yourself with one of three ways. If the metal tag is still bolted onto your diff cover it will say there. 2nd would be to jack up the rear end, mark the drive shaft and then spin the tire until it makes one complete rotation. Count the number of revolutions the drive shaft makes and that is your ratio. The third would be to pop the diff cover and count the numer of teeth on the pinion and then divide that by the number of teeth on the ring gear.
