Dart ignition switch removal

I've been all through this Dart (and related threads) trying to solve the dreaded "no spark but one spark on shutdown". Now I'm into the column and can't find the trick to getting the mechanical part of the switch out. Suggestions? Previous link gives me an error. It's a 74.

I know some you have to have the key in the cylinder to get it out and some don't.
Is yours like one of these?
