The SS option on the Nova is often discussed and many folks have questions. The SS package had only a few cosmetic features...and no connection to all the other interior or exterior trim options available on any Nova.
The Nova Resource website is a good place to go for info.

This link will take you to the SS option section where all features are listed...just select the year you want to look at.
