it's this section that looks to be of interest;

There is also a 1940-41 1-Ton T-116: CANADIAN DODGE DC2-20 T-116-120 120” w.b. and DC2-33 T-116-33 T-116-133 Serials # 8916601 to 8918281

I didn't grasp that it only covered 1680 trucks, but there you go. It was the split between T-116-120 ( have to be pickups ) and T-116-133 ( panel or pickup ) that would have told me what I needed to know.

However the fact that all the census numbers you have were for use as ambulances suggest that all the ones used outside Canada may well have been 133" panel ambulances.
