how long to replace the transfer case

[Ed*]

Hey folks I finally tracked down a transfer case with a new chain for my 1995 RRC and hope to start work next weekend on it. I dont have a garage (down side of city life) but I have a friend who will let me use their driveway.

So what im wondering is how long should I expect this job to take. I know that anything evil can and will happen when I work on the rover but barring any crazyness, what kinda hours are we looking at. I just need to be able to tell him how long his driveway will be out of use.

Thanks

with out experience and doing it on the ground I would say a conservative weekend....
of course in shop environment it takes about 2 hrs.. book time I believe is 4hrs.
