SS Identification?
1. Is the SLP SS version.
2. Is the Chevrolet SS version.
How do I verify which one it actually is?
Check the SPID sticker for the RPO code "WU8". If it has this code, then it's an original SS. If not, then it isn't.
A real SS is also a Z28, because all SSs started off life as a Z28 under the skin. So you will also see the "Z28" RPO on the SPID sticker in addition to "WU8", if it's an SS. Other official documentation such as VIN reports, etc., may also say Z28 since the VIN number does not directly indicate SS or Z28.
You can use sites like Compnine (listed above) or any GM dealer to run the VIN and provide a VIS report that will list all RPOs for the car.
The "Y2Y" RPO mentioned above was initially only present on SS cars that received additional SLP content above and beyond the base SS package. But starting in '01 or '02, this code was present on all SS cars even if they had nothing more than base SS equipment. "Y2Y" does NOT replace "WU8", but would be seen in addition to it.
