Swapping Command Trac to Select Trac???

I have a 2001 Cherokee Classic...I want to swap my Command Trac out for a select track...Is this diffcult or is it just a switch job?

As long as you get the right tcase (they vary in number of input splines and input shaft length... I forget what years the changes happened though) it should be pretty direct. Drive shaft length might change... but I dont think so. And shifter linkage might change, but I have no idea on that.
