Am I reading the eBay auction description correctly in that it states that there is only one documented '69 Z28 coded X11 (not counting the car in the auction)? If so, I'm confused and must be missing something because there are a lot of cars out there where the owner claims to have an original '69 Z with the RS option. I would have assumed that some of these would have been Norwood built cars, built after the X codes came into being, and would have had X11 on the cowl tag.
