May I just add that responsibility for production of cabs layed initially with Fords but axles/suspension layed largely with GM of Canada. This was as a result of experiences with the 1938 G/S 15-cwt Chevrolet trucks that the DND purchased. Failures of king-pins and axles resulted in belief that the 1940 Ford front axle was not strong enough for the production CMPs and so reliance was made initially on either McKinnon/Timken and/or Marmon-Herrington/Timken components. I like to think that Oshawa designed the GT drive-train, Windsor the cabs and possibly Brantford the GT bodies albeit based on the two British designs imported as patterns.
