I've just replaced my steering shaft and column and need to change the ignition barrel (Where you put the key into the ignition) of my old column to the new one. I can't see any bolts on how to undo it and obviously don't want to break anything. Any suggestions?

 

The entire cast aluminum switch assembly comes off. Grind a slot in the 2 mushroom shaped screw heads I've pointed out in blue and then use a screwdriver to remove them. The switch assembly is now free of the column.

You can use "plain" screws to re-assemble. The round ones are there as an anti-theft measure.

 

Great stuff thanks alot.
