1st Option - Pajero Gen 1 has IFS Diffs. Thats what I have used for both front and back. Need alot of alteration.
2nd Option - MB E220 diffs are independent.
3rd Option - alternation of any suitable tube diff into an independent axle diff.
Lots of option, depending on what you are willing to experiment and your patience level with the mechanic of explaining how to do it
