Direct from the Sloan museum. Many thanks to Andy for his help in this research. For 1969 - 1972 models. All 1969 factory Gran Sport Stage1 cars, both hardtops and convertibles, were built in Flint MI only (plant code 'H') All 1970 factory Gran Sport Stage1 cars, both hardtops and convertibles, were built in Flint MI only (plant code 'H') In 1971, all 81 factory Gran Sport convertible Stage1 cars were ONLY built in Flint MI (plant code 'H'). The 801 hardtops were built in one of three plants - Flint MI (plant code 'H' - 612 cars), Framingham MA (plant code 'G' - 56 cars), and Freemont CA (plant code 'Z' - 133 cars). In 1972, all 81 factory Gran Sport convertible Stage1 cars were ONLY built in Flint MI (plant code 'H'). The 728 hardtops were built in one of three plants - Flint MI (plant code 'H' - 463 cars), Framingham MA (plant code 'G' - 147 cars), and Freemont CA (plant code 'Z' - 118 cars). I hope this clears up a couple things for everyone.
