Done!
I took the opportunity to clean a bit the Brazilian models. See here for explanations about the name (Willys without Overland, Jeep without CJ-5) and the possible model years (1955 or 1962).

The single 1966 identification is due to bob dieck, but the linked "source" is a forum in which the contributors seem more to say that they're unsure of it, for me... Should we really keep this MY?
