There was a July 5, 2005 post in camaros.net by 'HawkX66' that might interest you:
https://www.camaros.net/threads/ya-coded-n66-ss-style-wheels.469621/In that post, it was said: "I'm going to have to read up a little closer on these wheels I think. This was posted by William over on CRG:
"RPO N66 "Sports Wheels for Camaro SS" were a short-lived option, dropped at the end of calendar year 1968. Chevy records indicate 314 cars were built with them. A few months ago Kurt located a window sticker from one of them, the first I've seen."
By "Kurt," I wonder if they meant KurtS from camaros.org? If so, maybe KurtS can post the photo of the original Instruction Sheet #3984091 for a 1969 coupe with N66 SS wheels? Kurt, if you also have a photo of Instruction Sheet #3984092 for a 1969 convertible with N66 SS wheels, could you post that one as well?
