Start here, looks like black to me. What does the trim tag say?
Also if you havent already call GM and ask for the info pack to learn more about the options:
A: If you own a US-built car, call the Chevrolet Customer Assistance Center at 800.222.1020 (toll-free US number), tell them you are restoring an early Camaro, and would like some data to help your labor of love. They will request your VIN, and then ship you a package of documentation that includes a detailed and extremely (though not perfectly) accurate specification of that year Camaro and the options. This, unfortunately, does not include option or configuration information on your exact unit (see the Car History FAQ), but it is free! And it is worthwhile.
