Re: turn signal cancel switch

How wide is the gap between the shroud and wheel? It needs to be fairly close -- 1/16 to no more than about 1/8". If farther than that the pins will skip over the metal triangle piece that releases the spring so switch can snap back.
If that distance is good are both pins on the wheel and with wheel removed and switch activated for one direction or the other, can you see that one of the points on the metal triangles has moved into a position so it will be closer to shaft and in line to get moved with the pins. If so move the point just as the pin would do and does the switch cancel?
If the column and shroud needs to move closer to the wheel there are two clamps -- one at the steering box and the one under the dash. Those both loosen but the column may not move up because of the upper inner bearing race which is a snug ring that is on the steering shaft won't move to let the bearing slide up with the column.
If the ring prevents movement, to get the column to move, with the wheel still fastened measure the amount the column needs to move. Remove the wheel and spring to slide the concave ring up slightly then loosen the clamps and move the column up. You may need to use a screwdriver or something at the steering box to pry it up the required amount. Tighten the bottom clamp and then slide the concave ring back into the bearing and reassemble the spring and wheel and check things out. If it cancels tighten all the clamps and if not and needs to move more, repeat the process.
Here is a 47 assy. The switch is different but the concave ring that needs to move up is the same as yours.
