I bought this from a member here on the forum thinking this would work for my 69 Skylark, but the wiring and the connections are wrong. I know it's a Pontiac part, but I thought I'd try here first before ebay. It's new in the box, complete rear seat speaker add-on kit from GM for Firebirds. Group #9.665, part # 988854. I'm not sure what years it fits. The box is a little worn and has 70-72 in black marker on it. It has all the parts and directions needed for install. $100 shipped to the lower 48.
