It was me, and I got it out and back in that way. Unfortunately it was some years ago and I don't recall all the details.
Start by removing the control head, wiring and stator tube, of course. I find it easier to leave the wires in the tube unless you're planning on replacing them. Set a pan under the steering box to catch any drips of leftover oil. Then I removed the coupling and inner upper column (along with the steering wheel). The column probably doesn't have to come out, but I was replacing the upper bushings, so I pulled it.
Disconnect the Silentbloc from the drop arm. Again, I removed the entire center link because I was working on it too, but it probably doesn't have to come out. Two bolts hold the steering box bracket to the frame, plus loosen two more bolts that clamp the box to the bracket. Looking at a photo of the area, I think the cross tube has to come out, but I don't recall removing it.
Loosen the upper bracket, and slide it up the tube. You should now be able to move the upper end of the lower column both up and down, and left and right (from the car's point of view), within the confines of the bracket on the frame and the timing housing on the motor.
Not sure if it is necessary, but I took both motor mounts loose so I could jack the engine up a long way. It has to come up and to the right enough to let the lower column rotate to the right and up past the bracket on the shock tower. My car also had the throttle linkage bent, which may have allowed the engine to come up more. If you find it pushing on the linkage hard enough to bend it, you might want to take the linkage loose from the firewall.
Once it's out of the upper bracket, then it's just a matter of maneuvering the box up and over the box section of the inner wing. Seems like I remember having to turn the shaft a bit, to move the drop arm so it would fit through someplace.
Here's a photo that might be helpful:
