I guess Chevrolet never built any COPO Camaros or Chevelles or any other special order vehicles for a specific use by a customer. To say this truck was never built is unrealistic. We have all seen one-off or limited production vehicles built that weren't "in the book." I don't profess to be an expert but this truck looks legit to me. I don't know who the family got their info from, that was before they asked for my help. I was just looking for a little help from the "experts", sorry I wasted your time.
