Yep; you are correct Fishy,I certainly agree with you. I also know that these years were not the greatest quality control years.I have talked to a bunch of the line workers and I myself have worked in all the car plants in St Louis as a carpenter/Millwright.When you see these cars going down the line and the parts being put on you understand that one day this guy is a ditchdigger and today he is an electrical installer.Yep they had a build sheet but if the parts didn't match use what you got.
