Zj Swap '01XJ NP231 & AW4 into '98ZJ TSi

I have an '01 XJ sport that I killed the engine in. I just got a '98 ZJ TSi. The viscous clutch in the NP249 seems to be at the end of its life.

I am wondering if I can swap the AW4 and NP231 from my XJ into my ZJ. I read a write-up on the topic, but I am not 100% if it's just a direct swap.

The transmission in the ZJ acts a little funny when cold, and the AW4 from the XJ runs flawlessly. Had the NP231 rebuilt a few years back, and it seems to operate fine. So I'd like to keep the XJ as a parts donor for when the inevitable time comes for the ZJ to require work.

Thanks in advance!
