Detroit Assembly
Detroit Assembly (also known as Detroit Cadillac, Cadillac Assembly or Clark Street Assembly) was a General Motors automobile factory in Detroit, Michigan on Clark Street, south of Michigan Avenue (U.S. Route 12). It began operations in 1921 and Cadillac bodies were supplied by Fleetwood Metal Body in 1921 after Fisher Body assumed operations. It was the second location that built Cadillacs, when Cadillac originally started out as the Henry Ford Company which was located at the intersection of Cass Avenue and Amsterdam Street. Engine block and cylinder heads were cast at Saginaw Metal Casting Operations then assembled at  Tonawanda Engine before delivery to Detroit Assembly for installation. In 1902, the Cadillac Motor Company began operations, and began building cars at the all new Clark Street facility in 1921, where the factory manufactured Cadillac models until December 23, 1987, when production of Cadillac's full-size D-bodies moved to Arlington Assembly in Arlington, Texas, while production of downsized FWD DeVille/Fleetwood/Seville models were relocated to Detroit/Hamtramck Assembly and Orion Assembly by 1985. It is approximately 2 miles southeast of the original Lincoln factory located at 6200 West Warren Avenue. All Cadillac vehicles were built only at  this facility, with production of popular selling models later added to Linden, New Jersey, South Gate, California or Arlington, Texas in "knock down kits" starting in the 1930s to meet demand. The bodies were built by Fisher at Fleetwood Plant #18 at 261 W End St, and transferred by rail to Clark Street for final assembly. From 1984 to 1987, the plant also built the Oldsmobile 88 and Custom Cruiser, and the Chevrolet Celebrity and Impala. Detroit Assembly used the VIN codes "Q" and "9." The site of the plant was redeveloped into the 88-acre Clark Street Technology Park  in 1997 by General Motors and three other partners. It is now the location for Inland Waters Pollution Control. LaSalle Factory/DeSoto Factory. For a brief time Cadillac's LaSalle was built at a separate factory in Detroit called Wyoming Assembly at 6000 Wyoming Avenue just north of Ford Road west of the Ford Drive-In Theatre. It was built in 1917 to manufacture Liberty Engines for airplanes used during WW I, then the factory was used by Chalmers Automobile to build the Saxon automobile until 1922. General Motors bought the Chalmers Plant in 1926 and 1927 built LaSalle cars  there. The factory is adjacent to the Dearborn neighborhood and is 2.75 miles west of the Clark Street Factory location. After LaSalle was no longer manufactured, it was purchased by Chrysler in 1934 and became a DeSoto factory until that brand was cancelled in the early 1960s. The factory is nearby railroad tracks which were very busy supplying coachwork from the Fleetwood Factory or other Fisher factories within Detroit and shipping finished product to cities across the United States.
