You will need to go with an adapter to run your pass side drop T-case for sure. Your clutch will work fine but you will need the slave and everything from the pressure plate back I believe. But the engine adapter is the same as well as the input shaft. If you're planning on pulling with this though I would run the 4500 because you can get the larger input. I know the X members will also need some attention.
There is a guy on the DTR that has done this. Maybe try and post it up over there to see if he'll chime in.
