4 dr Satellite?

Looking at a 68 2 dr post Belvedere...but the guy is saying it's a Satellite but I told him it's a Belvedere. He also says he has a 4 dr Satellite for a parts car. I don't recall any Satellites being made as anything other than a high tirm hard top....comments? I know the 1st two digits of the VIN will depict a Road Runner from a Belvedere but what about a Satellite?
