Accessing Radio Connection In a 1969 Valiant

I hear you about the manual. I'm about to go and work on it. I'll look for a screw near the bezel. The metal piece that houses the ash tray light only had 4 screws(which I removed) and is totally loose now. I just can't understand how to pull it. I don't see a space large enough to slide it out anywhere. I don't want to force it and bend it out of the space. I'll get back to you and let you know what happens. Thanks again.
