Just an FYI, but the "9" adjacent to the paint code means the car is painted in enamel (typical for Canadian Chevelles & Beaumonts) rather than Magic Mirror Acrylic Laquer.
The date for the dropping of the Sports Option seems to be Nov 21, 1966. As 68sd pointed out, the presence of D55 on the trim tag means that your car was built after the Sports Option was discontinued, so your car would have been trimmed as a Custom with optional bucket seats and optional console.
