t-case swappage

Does anyone know if the input shaft from an np207 is compatible with a 231 or 242? I need a 21spl t-case as an upgrade, but can't find any near by. If I could simply use my 207's input shaft on a different model, I would be very pleased.

Also, what driveshaft would be compatible (length-wise) with the front of my 2.5/ax-5/207 (231/242 if I can) XJ?

I managed to mangle my front X-member, what size sledge should I use? haha. And no, I didn't manage to push out/pull in my "frame" in the process of mangling it, the inner welds thankfully pulled themselves apart, thus sparing my poor frame...

Id give Novak a call.

This was kind of helpful, but I don't feel like tearing my t-case apart just to find out if it looks like any of the other input shafts:

I plan on upgrading to an ax-15 in the future, as such I don't want to spend much on this quick fix... thanks for chiming in, I'll call them during the work week.
