Just want to point out that a NV3500 will be a challenge to put in a jeep. I found out the hard way. A 3500 is a full size tranny with a tail shaft. It is too long for any kind of meaningful drive shaft to the rear wheels. And, the transfer case linkage would be a real challenge. Was too much of a hassle for me, so I found a NV3550. Worked out great.
