Dakota/Durango drivetrain in an Abody?

i plan on eventually ditching the torsion bars anyway. At least i think i lose them with the Alter-K-tion. not entirely sure tho. this is just an idea to play with since a durango/dak near me is far easier to find than an old mopar as far as parts are concerned. does it make a difference to me if the truck is 4x4? can i still use the rear out of it regaurdless?
