anyone with a 6.0 4l80e in a 4x4

[timcrow00]

ive heard of some people putting the 6.0 and 4l80e and their 2wd trucks but ive been lookin into doin the swap into my 72 3/4 ton 4x4. i know i would need the ecu and everything for the motor and trans, but can i use my original transfer case or do i need to use the newer transfer case. and what about the the shifter linkage for the trans and if i use the newer transfer case how would i shift it from 2wd to 4wd
