I run a passenger drop axle, I used a Dana 300 behind the stOck 231 case using a crawl box setup on the 231. the floor is modified enough that I could no longer run a bucket seat in my Comanche, I needed to run the bench seat. Not sure how that would work out in a Cherokee. It was very tight clearance for the drive shaft to the oil pan, I cut the oil pan and relocated the pickup inside. I also have two notch out one little corner of the transmission bellhousing on my AW 4. I am running a very skinny drive shaft to allow it to fit, and it is still very tight I have very very limited of travel because of the drive shaft clearances.if you were running 5 inches or more of lift, I don't think you will have nearly the problems that I had.
