This is exactly my point... Good luck finding one, they are pretty rare, and when someone does have them, they usually want an arm and a leg for one. In my opinion its not worth fooling with. Are the Dana 44s good? Yes, they are. I run them front and rear in my rig with 38's and I am happy with them (but not in a cherokee). However, for a Cherokee application, the 8.8 is really the way to go. They have axle tubes that are 1/2" bigger so they don't have bending issues, they come from the factory with disc brakes (and yes, your master cylinder and proportioning valve will work them just fine), they are the correct width, and they have the correct bolt pattern on them already. I personally don't see a reason to go with a 44 over the 8.8 other than it is not 100% bolt in. But from what you have said, I don't really think you care too much about that.
