- Central Specialty was located on Norris St, near Forrest Ave. It had its own casting and machining facilities, with a separate engineering and administration building across the street. Today, some of the manufacturing plant still exists. The casting facility was torn down after Motor Wheel took over in the mid-1960s. The engineering and administration building is currently the home of the Corner Brewery bar and grill along with the Arbor Brewing Company micro-brewery.
