For Alan's attention: The window sticker doesn't show the Sunrays as an option, however using the OFS, pg G7-8, on the ROT sheet, Row 3, Field FS-WC, Code '1', would indicate this car was equipped with 'Full Wheel Covers w/Fender Skirts'. What do you make of this? By this time, had Sunrays become standard equipment?
Thanks for posting - great info! To clarify, full wheel covers were standard equipment for 1960 without the Sun Ray trim. The Sun Rays with the added trim and tri-color plastic center would have been called out on the window sticker since it was an added cost item. If your car has Sun Rays, it means that they've been added after delivery from the factory, either by the dealer (which probably would show up on the dealer's sales invoice/bill of sale) or someone else. After all, Sun Rays were a factory- and dealer-installed option.
