When we ordered the Yellow car with the extra cost L89 ( Iron head delete ) option we couldn't afford the radio so we didn't check the radio box. WAG

SS dashes would have a plastic grained plate while a malibu dash had a steel cover plate and monte had a burlwood cover plate. I have had few of each over the years.

The dealership my Dad worked for didn't order radios in the cars and trucks. Dad would install whatever their customers decided on. Some were Brand X and some factory accessory radios. He had a box with radio plates and wiring piggybacks that I found in his stuff. I have since used or sold most of them. They were in a Chevrolet Radio box.
