1970 Dart radio removal tips

Hi all!
Im starting to work on the new-to-me Dart now that spring is finally here in the northeast. I'd like to remove the radio which isnt currently working, and id like to do it without breaking anything (especially the 50-year old plastic bezel). I understand that its not the original radio, my guess is a '73-ish that the previous owner installed. Any surprises I should be aware of? I felt behind the dash and I don't believe the radio is screwed in that little security tab back there.

Neither service manual i have has a clear diagram to show the number of screws behind the bezel, etc. Do you just remove the radio/ heater knobs then unscrew those two screws on the bezel? Is it pretty straightforward in there? Mounting screws and a few plugs? just want an idea of what I'm getting into back there before I do it.
