What do you want to know? There weren't too many options on the SS, so a VIN isn't going to tell you much.
They all had the LS2 6.0L, 4 speed automatic, limited-slip diff, tow package, and 4.10 gears (don't think 3.73 was an option).
You either get the 1SS or 3SS. 3SS got you dual leather power heated seats (w/ driver memory), power pedals, steering wheel controls w/ DIC, auto climate, home link, and some other stuff.
If it has cloth, it's a 1SS. Be careful, some dealers have put leather seats/covers making them look like a 3SS but you can easilly tell by the lack of steering wheel controls and manual hvac settings.
