<VV> Early ignition switch cylinder replacement.

[Norm Wright]

 I recently acquired an early with no key, and the ignition in the "on" position.  After trying every one of my collection of B-10 keys with no luck, I got another cylinder with keys.  Now the problem;  How do I remove the useless cylinder when I have no key to get it into the lock position?  I'm thinking I may have to resort to hammer and chisel tactics, which I hate to do to any Corvair.
