As we never had a manual trans on a CRD here state side, I would hate to venture a guess as to input shaft length and so forth.

Sending a PM to merlinTec might be a good idea as he is well versed on the Euro models. He may shed some light as to the swap and it's possibilities.

See this thread from last summer about a guy wanting to do so with his TJ:

Believe me, I love having the option of full-time four-wheel drive in my KJ. About a week ago I towed a trailer over the Rockies and then another 1,100 miles and it was great having the option of full-time for the mixed road conditions of ice, snow and dry pavement where I wouldn't have wanted to use part-time. With full-time I was more comfortable keeping my speed up with the rest of traffic.

The 242 will cause driveability issues when in fulltime 4wd with manual trans,and why the 242 was never offered in a KJ/XJ/ZJ/WJ with manual trans.I would highly advise against it.
