I just swapped mine power sterring box to a manual. It is not complicated but it sure is a beast to work on it. I found the 3 bolts that hold the box in place a real pain to get at and even worse to get back in, I didn't have much room to work and it was done under the car. Try to get the car raised as much as possible. The other thing that you will almost certainly need to do is unbolt the motor mounts and jack the motor up on the drivers side to give it more clearance to get the box in and out. I would also take out the battery and tray out to give more room to take out the box.
