Can anyone tell me the name of this part?

It's a light panel on the interior rear panel right behind the door on a 69 convertible. There's one on each side (or at least their should be) and they are missing from my car (the bulbs are there on one side)

I'd like to try to find the parts if possible.

Those are your rear-seat courtesy lights. On a coupe, they'd be on the sail panel. Since you have a convertible, they were relocated to the ends of the rear side armrests.

Thanks! Are they normally square?

I saw some sail panel courtesy lights for a similar year Cadillac on eBay and I was thinking of getting those as a replacement.

I believe they are rectangular for the convertible, owing to the narrowness of the ends of the rear side armrests.
