Default JK Transfer cases

Has any taken the 2.72 transfer out of a JK Unlimited 6 speed manual & replaced it with the 4.0 transfer case (rock trac) out of a Rubicon ? If you have, please let me know what was involved. Thank you..........

Direct swap. Unbolt the driveshafts, remove the old tcase, install the new one, reconnect the shafts. There may be a slight difference in the outsides of the cases, but they mount up the same...

Nope. The 4:1 would be nice, but I'm looking at the rubi-crawler and atlas instead.
