Graeme / New Zealand, You are correct in saying that the Park Light Lens on the Canadian Mercury Trucks, and the Australian 1948-1950 Ford Trucks are the same as the 1942 early 1947 passenger cars, however, the Chrome Surrounds are different. The 1942 Frame was only used for that one year and had fancy ends. It was changed for 1946 early 1947 when it got a raised center with "hash" marks. On the Trucks, they were totally plain,as shown above.
