I believe that the Norwood plant was the only plant making Camaros and Firebirds in 1972. The United Auto Workers went on strike in April of 1972, shutting the entire plant down until the next model year. That's why 72 is probably the rarest year for F-body total production. (only 458 4-speed Trans Ams were built). When the line went back up in 73, they ended up scrapping thousands of partially completed cars due to the fact that they did not meet the 1973 emissions and bumper regulations.
