Some more pictures. Disassembled the column today. - It's not possible to remove the inner tube completely. It holds the lower part of the shift collar. It's centered by a metal bracket on top and by a plastic sleeve at the bottom, where the neutral safety switch mount. I will cut it just below that. - The inner tube turns, and moves the lower collar. It blocks the removal of the key when not in the correct position. With the tube cut, I need to hold it in position. At the bottom, there are to screws holding the plastic sleeve mentioned above in place. I will take longer screws to hold the tube in position. - The other option would be to grind the lower collar. In the second picture, you can see a long tab at the bottom, this is what gets pushed in between the bracket that is moved by the ignition key. But I think I will go the other route. - The 1" DD tube fits the upper steering shaft perfectly. Still waiting on the correct u-joint, the one in the picture is borrowed from a friend. - I will make a sleeve for the bearing out of the chunk of aluminum on my lathe, and put it in the column from the bottom. Will post a picture hopefully tomorrow.
