I have a Canadian built 46 3/4 ton that we are slowly taking apart.It has 8 bolt 17 inch split rims so I am surprised to see yours are 6 bolt. For a 3/4 ton it has the short box and was set up with a hydralic dump and we found a weigh slip from the saskatchewan wheat pool dated 1980 something.If my memory serves me right your Maple Leaf truck would have come from the Oshawa GM truck plant or posssibly from a plant out west. The canadian Gmc trucks had the chev 216 not the 228 Gmc engine ? Let me know if there is anything on our truck that may help you out identifying yours.

First time I saw this truck I said "That's the one!"
