General Motors Medium-Duty Class 6 Trucks in the 1967-1972 bodystyle (also known as the Action-Line generation) being produced at the General Motors Truck Assembly Plant in Flint, Michigan.

These particular General Motors Medium-Duty Class 6 Trucks pictured coming off of the Assembly Line at the Assembly Plant in Flint, Michigan; have been built with the Dayton-style Multi-Spoke Wheels.

I, personally like the Dayton-style Multi-Spoke Wheels; instead of the Budd-style Disc Wheels on Class 6-8 vehicles.

The General Motors School Bus Chassis & Cowl in the Action-Line generation, might have also been produced at the Assembly Plant in Flint, Michigan. The General Motors School Bus Chassis & Cowl in the Action-Line generation would go on to be produced for 11 more years after the other Medium-Duty, Medium-Heavy Duty (Class 7), and Light-Duty Trucks in the succeeding 1973-1991 bodystyle had first gone into production in late 1972 for the 1973 model year. It would not be until late 1983, for the 1984 model year; when the School Bus Chassis & Cowl in the 1973-1991 bodystyle would finally go into production.
