WAGON REAR LICENSE PLATE HOLDER. According to the parts book, USA wagons received the characteristic folding license plate holder on the lower rear tailgate in 1961. This holder uses the ubiquitous Lucas license plate lights. The folding license plate holder was used on American wagons until Citroën stopped importing cars into the USA in 1972.

We think Canadian wagons received the folding license plate holder at the same time that USA cars did. Note that Canadian license plates are almost exactly the same size as USA cars.
