This is for a car I am looking at. I do not have the build sheet. The ship date on my PHS Docs is 7-18-78. I am thinking it had the 4-speed originally. It is easier to install an auto shifter than the clutch pedal. However, this isn't a W72 car so I am a little confused. Based on one of the production numbers pages, it should be a W72 if it had a 4-speed. Was it possible to have a 4-speed and one of the other two engines?
