[COPO PETE]

What's the correct answer. My COPO Chevelle has the -- paint code. It came Daytona Yellow and is documented by GM of Canada as such. I read once where Daytona Yellow was available only on the SS Chevelles in 69 but not the non SS cars. Is this why my car has the -- on the tag? Was Daytona Yellow available on SS cars? Has anyone else ever seen a Daytona Yellow COPO Chevelle, or is mine the only one?
