The tail light filler panel on my 89 Formula is missing the trim around the keyhole. Can that piece be bought or do I need to find another filler panel?

The trim around the keyhole in this pic is what I’m missing.

 

I'm not sure if anyone is reproducing them but they can be popped in and out pretty easy.

 

The firebird/formula 85-92 filler panels are the easiest and cheapest to find. Salvage yards, ebay, craigslist, facebook marketplace. But if it was me, I would post a wanted ad in this site's classifieds. I'm sure someone has that trim piece on the classifieds here and would sell it for fairly cheap.
