holy ****. i wouldnt even fathom doing anything like that. i hope he knows the axles in xj's are very weak. most of my xj friends put in full size axles and are actually thinking about converting to leaf springs in the front. but if you have the imagination and A LOT of free time on your hands, go for it.

dana 44 in the front, ford 9" in the rear and detroits in both. we just put a 350 in this truck and all it needs now is the radiator. it puts my yota to shame though lol.
