I must correct you on the factory reverse lights avialable on the '66 C10, C20, K10 & K20 with the factory equipped SM420 four-speed on the floor manual transmission. The reverse lights became available in 1966 on these models. Attached is a picture of what the assembly looks like.
\'66 Chevy Truck Reverse Light Assembly I hope this information is helpful and clears up the availability issue of reverse lights as a factory/dealer option in 1966.
