The AMC20 is a strong rearend if you build it, upgrading to a dana 44 is not upgrading, more or less sidegrading. I do have some waggy front and rears, the only bad thing is the front is a driverside drop. not sure of the gear ratio tho. I am going to send you a PM, give me a call, I have been writing a couple of Ideas down on building a good trail and dd jeep. Just going to run them by you, plus I need some more jeep buddies around to go to Disney.
