Ignition switch question

[lutronjim]

I have a 69 cab on my 70 truck (don't ask) and it doesn't have an accessory position - can't turn key counterclockwise. I would like to have this for radio etc.

Will a 72 (or some model) switch work?

I also have another problem, I can't get cylinder out because key can be removed with switch in run position. I have read several post on removal with no key but I have one. Any trick from removal in run position?

Thanks
