Re: Cherokee and Pickup
'76 to '79 are the best choices, followed by '80 and newer. The older frames were different and if you swap springs, some parts may be slightly different. Stay away from '73 and older. '74-'75 may work too but the frames aren't as beefy as the later ones. The axles and drivetrain will swap into these. Whichever you choose, you may have to modify or swap your wire harness depending on which alternator and ignition system you have.
