Converting from 2wd TIB to 4wd TTB

[Gates.Ranger37]

How hard is it to convert from a 2wd drive TIB to a 4wd TTB?

They way I understand it right now is very simple. It seems like I'm missing something.

Correct me if I'm wrong, but all I would need is to swap my i-beams for traction beams, bolt on a transfer case, attach the driveshaft, and cut a hole in my floor pain for the manual shifter?

There has to be more to it than that. Someone please enlighten me.

Yeah new frame crossmember (requires removing the engine), disassembling the entire transmission to replace the output shaft & tailhousing (or just swap the whole tranny for a 4WD one) to allow you to bolt up the t-case, replace floor plate for the shifter (no need to cut holes in anything).
