I have the radio and heater removed, two screws on the radio side removed, electrical connectors removed, I can release the lock tab for the park/lock cable but can't seem to push it back far enough to remove it from the housing, also not sure how to remove ignition bezel and light ring

Do you
have the same problem?

Which one are you trying to replace? Is it the ignition switch or the ignition cylinder lock?

I don't know how to attach photos, if there's a number I can message them to I'd like for you to see them so you can see I'm not crazy.
