Here is what I found in my book for the 5/4 ton cam pattern. It is not the usual drawings found for the Cdn cam patterns, so may have been a provisional. I do not believe it is any different than the pattern you would find on the older 3/4 ton trucks.
The patterns for all the vehicles could be found in the manual of cam and concealment (CFP317 or 318 or something like that) from the 70s and 80s.
