Does someone run such a thing, 1971 GTX Registry. An owner of a 1971 GTX 440-6 Gold in color with a build date of July 9th, 1971 was asking if his was one of the last GTXs built and one of the last 440-6 Xs built. I do not have the plant it was built in or the serial number but he lives in New Jersey. He bought the GTX in July of 1972.Even if there is no registry does anyone have information on any GTXs built in July of 1971.
