steering column and gear box

[blownford]

Back in the '90's when parts and shipping were a fraction of what they are today, I gathered up original parts I thought I might need in the future for my '36.
I heard that the 1937 gear box was much improved over the '36, so I bought a box and the required bracket to install it. I rebuilt the gear box and it's been in my attic all these years. I later discovered that my banjo wheel was a 1937 which made me curious and after investigating I found my car already has a '37 column and gear box. I also confirmed they used the correct bracket from a '37.
Now the gear box in the car has worn out and I'm installing the rebuilt unit.
Question, can I remove the entire unit in one piece? looks like I could remove the wiring going to the switch and the bolts holding the column to the dash and bring the column/box assy with the steering wheel attached up through the floor and out of the car. I could then swap the parts over to the rebuilt unit on my workbench and not trying to drill pins out etc from under the dash.
Any help appreciated.
