Note that many US WW2 and post-war vehicles also used the Trico S Series, but there are detail differences with the models used on Canadian vehicles, particularly the mounting dimensions. Jeeps and Dodges used the S 583. The Canadian applications seem to have a simpler design assist lever than the US versions.
While it relates to the physical dimensions of a post-war S Series unit fitted to a CJ2A Jeep, there is a good re-build write up of these units here:
