D80 code is the Air Spoiler option and not part of the COPO 9560 or 9561 option.
There is no Official COPO list other than what individuals have compiled over the Years (Yenkos, ZL1s and Canadian sold COPOS excluded) |

Late COPOs ordered by Yenko would have X44D80 as all were ordered with the spoiler option. However, many COPOs, ordered by other dealers, were ordered without spoiler, and those would be X44. (or X11 if style trim was selected)
Look for other indicators of b/b....like tranny cross member, single fuel line, outside heater box, frame mounts, etc. An X11 with b/b from the factory, would absolutely be a COPO. Also look for curved neck radiator, 12 bolt rear, front discs, etc. If it has a few of these things, I'd be getting excited...if it has all, I'd be getting extremely excited! |
