I don't see why not. What transfer case are you using now?

One New Process transfer case being swapped for another. Same bolt pattern to the transmission, same clocking position, same electronic speedometer interface plug, the shifting linkage looks like it works the same way, the front driveshaft should bolt up just fine...The rear driveshaft might have to be changed. That's the one issue I see with this thing.

Make sure the imput shaft matches, too. Some of them are different length and have different spline counts.

This is something I would normally think about but don't all the ZJs have 23 spline input shafts? This guy is using a NP249 so what does the NP231 come from?

Not schooled on ZJ's but the NP231 is in TJ's and YJ's I believe, and maybe others, too. In those models I think there is a difference with the input shaft if you are auto or manual trans.
