Identify this part--Glove Box lens?

I found this loose (not labeled, not bagged) in the garage. I have '65 Barracuda and '72 Satellite. If this part belongs to a Mopar, it might be a cover for the glove box lamp, not sure. What do you think? On the inside is a number stamped in the center: "214" ("21" on top and the "4" is stamped just below the "21"). Thank you.
