47-55.1 Prep for Ididit column

[TX3100Guy]

I placed an order today for an unpainted (steel) Ididit column with turn signals, tilt, and horn (something my current column doesn't have). I've already pulled the entire steering box and column from the truck, which was made simple by the fact that I have the inner fenders, radiator, and radiator support already out of the truck.

I now have the steering box on the shop floor and have been trying to persuade the column tube to come loose from the steering box, so that I can ultimately get to the actual column itself for the future step of cutting it and grinding in the double D's (which is not what one normally thinks of when one thinks of double D's).

All joking aside, my question is how much persuasion is necessary to get the tube out of the steering box to expose the column? Any helpful tricks will be greatly appreciated.
