Looking for assitance

Yeah, and when you consider Dealer Installed options, it just keeps getting weirder. Like dealer installed AC versus factory AC, two different animals and the dealer stuff never shows up on build sheets or fender tags. When I worked at a dealer, things would regularly get swapped out or added to "make the sale"- add the trunk light, rear window defroster, swap the wheels and tires with another car...
Thanks one and all, I really appreciate your help. I know that I am correct and you have just proven it. Many thanks to all of you.
Professor Fate: I know what you mean. I worked in the parts department of a major GM dealer back in the 70's. If you came in and were looking for a Tee top Cutlass, or Camaro there was no 100% guarantee that GM installed those tee roofs. We had an outfit that could install them in a couple of days.
