Chevrolet Overview
Body Bank: Receives the body shell from Fisher, assigns VIN and stamps the hidden VINs, separates them by major Chevrolet equipment and option content, and schedules them in "locked" sequence to the Chevrolet Trim Line; specs for each car are "broadcast" to subassembly and feeder lines throughout the plant.
Trim Line:
Installs VIN plate, dash mat, heater or A/C system, wipers, pedal support, instrument panel, cluster and wiring, steering column, front carpets, console, brake booster, rear bumper and guards, and the rear shocks and fuel tank; installs the complete front sheet metal assembly and sends the body to the Final Line for chassis-to-body marriage.
