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.

You have to drop the steering column also. There is another bolt that can only be accessed from the steering column side.

As far as the "ignition bezel and light ring", they are part of the lock cylinder, which when you depress the metal tab through the radio opening, you have to get a good grip around the ring and pull the lock cylinder out. You may need to use a screwdriver to break it loose, but be careful not to gouge your dash. Once you drop the steering column you should be able to get better access to get the park lock cable out. The switch is removed through the radio opening. You have to twist it to get it out.
