By the mid-1960s, several other body companies (notably Blue Bird Body Company and Perley A. Thomas Car Works) maintained assembly plants at multiple locations. Instead of establishing multiple assembly points in the U.S., Wayne chose to replace the overcrowded and aged Wayne Works facility on E Street near downtown Richmond with a single new plant large enough to handle both manufacturing and assembly for United States production. Due primarily to Canadian import tariffs, the separate Canadian assembly plant (Welles, Ltd.) had been established and was maintained for Canadian production. In 1963, Divco-Wayne acquired Welles entirely, making it a subsidiary of the company.
