When you have given up hope, get your new parts and look at them. You will need a new steering lock and tumbler and the hardened black ring that surrounds them. Once you have the pieces you can put it all together in your hands and see how it works.

There is a pin that holds the steering lock in. It can be drilled, but you need to know where it is. This can be best viewed from the new one.

With the steering lock hanging under the dash from the harness the electrical part of the switch can be removed by strategic incisions through the switch cutting the three mounting bolts. It is probably best then to just throw away what is left - the steering lock/tumbler/retainer arrangment (less electrical switch).
