do i have a Caprice which is cloned to look like an SS or do i have a Caprice SS?
You have a basic caprice. We all do. As mentioned, searching for and cross referencing the RPO codes will shed light on what your car originally came equipped w/. Make sure the trunk RPO VIN matches the VIN on the dash. All basic caprice models (am limiting this to sedans here) came w/ varying levels of add-ons from the factory up to and including 9C1, 9C6, WX3 & WX8. This is documentable. What people/previous owners have done after delivery from the factory is undocumentable at least and very sketchy at most. This is what you need to determine.
