Re: column shift linkage frozen

The inner spring to return the lever could possibly rust but it's fairly substantial. The rod has 3 rubber anti-rattle bushings inside the tube which could have swollen and be binding the rod but would take a lot of swelling. There is a bushing affair at the top of column which could be causing the problem if it has dried up. Here is a photo of the disassembled lower end. The oil running down inside the tube only goes as far as the tongue affair and maybe out the slot to wick onto the splines to do any good. The rest just runs out the end of the open tube. My shift levers had almost completely corroded to the shift tube. If the tongue tried to move one, the other came along for the ride.
Other than the size and shape of shroud, I can't remember for sure how much difference there is between the 47 and 49. I think they are pretty much the same inner detail wise. At the wheel end, the large spring goes between the wheel and the upper bearing to keep bearing parts in place and quiet. I think the M shaped wire you mention is the same as this piece in the 47. I believe it's purpose is anti-rattle. That round post affair the wire presses against comes off with persuasion and under is the area where the bushing mentioned earlier is located and could use oil.
If you need to remove the column, the spring around the shaft presses against a part of the upper bearing (arrow) that usually has to come off before trying to remove the column. The shape of the ring compresses it against the shaft and acts as a retainer otherwise.
