sales brochures were often printed prior to production and sometimes items did not make it into production.
Yes, I know that. This is why I clarified my Statements.
In order to further clarify, the Brochures do not specifically say "Factory Option", so they could have also been "Dealer Options". In either case though, they could have been ordered when the car was ordered (unless of course something specific revised what was noted in the Brochures. Too bad someone doesn't have a Price Guide for these years like the one I Posted earlier in this thread in regard to the 1965 Visibility Group. However, I think that since these were "Color-Keyed", it would make sense that they would come from the Factory rather than the Dealer having to paint each one to match a specific car.
