In the last couple of years you could order an SS with some stripped-down details like cloth seats instead of leather, I don't know what all options you could delete but I'd be surprised if it included the steering wheel without controls. Take your VIN to the local Chevy dealer and have them print you up a build report on it. If they aren't cool enough to do that for you, you could spend $5 and run it on Compnine. It'll decode all your RPO codes for you and save you the hassle of doing it yourself.
