Big thanks oem4me for transferring this great photo to the assembly thread
. I agree this must the Canadian line. American GMC pickups did not have series indentification emblems, the first truck has emblems on upper cowl ( '65 Chevy location) The absence of V6 emblems is more fuel for the argument, but not enough alone, since straight sixes were available in both American and Canadian '64-'65 GMC's. I also agree the first truck sports a special order fleet paint job.
