Do you prefer auto or manual transmissions?
the ax-4 will not bolt to the 4.0L, so that's out right there. probably the easiest swap will be the most thorough. Gut the MJ completely and swap over everything from the XJ. :thumbsup: you'll still need a rear driveshaft (most of us get the 2wd shaft shortened), splice the MJ rear lights' wire harness to the XJ harness, and some exhaust work.
