I have four Canadian GMC and Chevrolet Maintenance manuals. One is for 1948 to 1951, one for 1947, one for 1946 47 and 48,and one for 1948 to 1950. As far as I know there are no reprints. I see them for sale every December at the swap meet in Mississauga. I would be happy to send copies of pages that might be helpful. Some of the instructions go beyond what is found in the US publications that are reproduced. There is information on the different series of trucks, the ratings and there is also information on both the Chevrolet and GMC engine series.
