98 Body Part Identification Help
 

Hey Guys! First post here so bear with with me. Recently had someone hit my Cav in my apartment complex. The usual no note, etc. Cracked my tail light and took a chunk out of a part I can't seem to find a part number on. Looked through parts diagrams and can't seem to find it. It's just below the taillight on my '98. Was going to order a new tail light, but figured I would hold off to see if someone can help me identify the other part. Thanks in advance!

What's the other original side look like?

car-part.com?

Probably just a reflector...?
