They did pull windshields for some re-paints. CSX2367 was repainted from blue to Highlander Green before shipping to Gotham Ford to fulfill the original owner’s order for a green street Cobra. I spent quite a bit of time with the original owner, Joe, when I acquired 2367 10 years ago, and he had stories about how some of the bolt on parts weren’t tight (like the wiper escutcheons) when he test drove it. The original invoice from Gotham has handwritten notes promising to repair the paint damage.
This history may have no bearing on CSX2345’s paint story. But it is clear that the factory was willing to do extra work to get Cobra’s sold in 1964.
