Grand Ams were made in 1973, 1974 and 1975. After 75 they were killed because of poor sales. The 73 is unique-its rear end, trunk and quarter panels are different than the 74 and 75 models. The front end on all of them was made of urethane, but the 74 and 75 front ends were different than the 73. I have castings of the 1973 Grand Am, a 1973 GTO front end for the Grand Am body, and a 1977 Can Am casting. After the 1975, I will do a 1977 Lemans 4 door sedan for the Smokey and the Bandit/police interceptor folks.
