66 Newport Backup Light Housing removal

I'm trying to remove the backup light housings so I can clean them up, replace the bulbs, etc. I removed the two screws that go through the lens, and the assembly kind of moves around, but the lens won't come off, and the housing won't come out either. Not wanting to break something while forcing the issue, I'm looking here for advice on how to proceed. I couldn't find anything in the FSM. Does the lens just pry off once those two screws are removed, or is there something else.

thanks!
