what is this stuff worth?

I have a guy who owes me some money, and he offered me some Conquest parts in exchange. He is giving me two complete 87 headlights with motors and two complete non cracked taillights from the same 87. He also said I got on front park light and the fog light bezels.

I am a Camaro guy, and I dont have a freaking clue what this stuff is worth. He owes me 300 bucks. I am getting the shaft?
