Fullsize cherokees in 1980 used a dana 20 that was flipped to use a front end offset to the drivers side, this will allow the use of a ford front end (dana 60 dana 44 dana 50) to be used, they arent bad with reverse rotation gears (means the ring and pinion are tougher) and coil springs, this dana 20 can be used with any tranny that had a dana 20 behind it)with the th400 to dana 20 stock setup, they used a special gear setup in the housing but it can be changed) cool huh? so go go coils springs, they articulate really well
