Now known as Flint Assembly, it remains an important operation for GM; it builds Chevrolet Kodiak and GMC TopKick commercial trucks, and Chevrolet Silverado and GMC Sierra full-size pickup trucks. In December 2004, GM announced it would invest $150 million into retooling at this plant. After a maximum of at least 8,000 workers at Fisher 2 and Chevrolet Assembly, 1,862 hourly and 185 salaried employees work there. Events at this plant during the late 1970s are chronicled in Ben Hamper's 1991 book "Rivethead: Tales from the Assembly Line".
