4.0/AW-4/NP242 in a CJ/YJ?

Disclaimer: First I want to say I have read and read on this and found parts about the engine or head swap, and parts about the trans swap, but none about the whole DL swap... so please assist if you can or direct me if you know of a good link, but I promise I have read TONS of the writeups and cannot find anything quite specific enough to tie it all together. Thanks...

I am going to buy my first Jeep here in the next few weeks and am watching CL and Classifieds. Though I have not counted out the XJ completely, I am leaning strongly towards a CJ or YJ. If I got a YJ it would eventually get the CJ front end and dash conversions, but I'd benefit from the suspension and MFI. I love the look for the CJs, though.

What I really am interested in is what it would take to get a 4.0/AW-4, and NP242 from XJ or ZJ in a YJ or CJ. I know the motor mounts would be the same for any I6 and there will be some minor wiring to do with the computer, etc.... but what about the transmission and T-Case mounts? Has anyone done this? Also, with autos on the column, should I get a CJ/YJ with standard and pull the clutch system or should I get auto and change the column? I know I will need 91YJ VSS to use CJ Speedo and 91+ YJ gas tank for fuel pump, etc. Any other suggestions or details?

It would end up with CJ grille and hood, tube fenders, CJ Dash, XJ/ZJ drivetrain. The radiator would be stock CJ/JY I6 or V8, fan would be eliminated for taurus electric. XJ spring length and SOA is likely, too... but that's another story.

Any other snags I should consider? Anything I missed if the whole computer and ECM and harness comes from XJ/ZJ?

How much would I need to swap, and where, for brackets? Which water pump if electric fan and possible OBA (additional compressor, keep A/C) later on down the line?

I thought someone maybe would have some suggestions or input? I'm just curious if there are stock crossmembers and mounting hardware to get the drivetrain out of a XJ into a CJ/YJ. It's the best of both worlds with the MPI, strong AW-4, and decent NP242/NP231... IF it will work within reason to bolt in.

(BUMP)
