The '57 Plymouth Fury is based off of the actual production model. However, this particular casting has a 1958 style lower valence panel. The grille shape is different than used in '57. It is also worth noting that Plymouth never actually produced a Fury sedan in 1957. The Fury for 1957 was only offered as a two door hard top. This car is based on a sedan as it has the "B" pillar.
