Backup lights and Radio were not always a delete. On a base model special, those were both options, as were alot of other items you would expect to be standard equipment on a skylark like 2-speed wipers with washer for example. The 65 Special 4-dr I used to have came from the factory with V6 engine, 3-speed manual on column, manual steering, manual brakes, single speed wipers, and no backup lights. That was all standard equipment on a Special. Only three options on the car were AM radio, remote drivers side mirror, and the day/night rear view mirror. The mirrors were most likely added at the dealer.
