Paper work that came with the car when first sold is the only way to truely tell on all Novas with the exception of 72 where they actually have a designation in the VIN#. The options sound correct, but they can all be bought off E-bay. You can check date codes on the options and make yourself more comfortable with the fact that it is an SS car, but the only way to know 100% is with origional sales documentation of the car.
