Canadian production figures are out there but not as easy to find plus the Mercury Meteor was a Ford in Mercury dress but I don't know what the production number differences would be between the Meteor model and the regular shoe box Ford of the same year. Same with the Ford Monarch since it is a Mercury in Ford dress. Canadian figures were a fair bit less than US production. There should be number stamped on the frame rail but they aren't always easy to locate. The stampings weren't very deep. Ford stamped firewalls with information too but it was usually body information stamped there.
