See photo below of red 1960 "Equipped Flightliner," which is what you appear to have. The reflector on the fender is not necessarily the size of the original, but I think it's close. Some other models and model years had reflectors on the back of the luggage rack like the silver Spaceliner in the second picture. The 1960 "Deluxe Flightliner" had twin tail lights that looked similar to the reflectors on the Spaceliner, but were battery powered.
Smooth riding, Andy
