The CRD has a 242J transfer case, the only difference MAY be the low range ratio, IIRC it is 2.35:1. The high range is 1:1.
AFAIK, the low range ratio used on the NP242 in the KJ is the same as in the other Jeeps that used it - 2.72:1.

For what it is worth, I believe the gassers also had the 242J. The 241 case WILL work, however it lacks the fulltime setting. I ended up with one of those after the high range imploded on a trip, and the boneyard THOUGHT that they had a 242... It wasn't correct b/c the owner of the wreck must have swapped it at some point just like I had to do. It worked for the trip, and then I had to get another (correct) case for the CRD. Now I have that as a paperweight and 2 more 242J cases that have been "inherited" from various projects.
Are you sure that NP241 isn't an NP241OR? If it is, it should have the 4:1 low range from the TJ Rubicon.
If it was a 'regular' 241, I believe that those were used in GM vehicles. No idea as to how easily those would interchange with a Jeep, however; could be a case of changing tailcones and output shafts (or something else entirely).
I'll buy that 2.72:1 ratio, sounds good to me. My number was just a fuzzy memory guess. As for the 241 case, it matched the physical appearance perfectly, fit exactly... Just didn't have the full-time position OR the NP241 tag to tell me precisely what it was. I couldn't tell you if it was an OR version or not - I don't think it was 4:1 though, that would be a CRAZY low range. My use of it was just in the 1:1 range, I only tested the positions after it was installed, but I was in the middle of nowhere Louisiana and had to get to Texas on that trip... So I wasn't too concerned about what range it had.
It was solid though, no crunchy noises like the case that had dropped the high range on me on an off ramp! When that one was cracked open... Mmmmm, yummy steel oatmeal all up in there. Dumped that sucker in the scrap heap.
