Thread: How do I tell if I have a true SS

Tweet

You can't tell by the VIN. You need the original paperwork, or the build sheet that show RPO Z26. There were 35,542 SS Novas built in '73.

1973 thru 1976 SS = optional package: these are the hardest years to verify. Original paperwork is really the only way. In 1973, any engine could be ordered in the Super Sport including the 250 L6. Because there was no "SS-only" engine, there is no way to verify it as real by the engine codes. Also, disc brakes were NOT part of the Super Sport package in 1973-74. All 1975-later had front discs standard but power assist was still optional

There is often a build sheet buried somewhere in the car. I'm not sure where it its an a '73 Nova.
