47-53 are all about the same, except a few minor changes. One change is they went from no side vent glass to vent glass on the doors. 1954 and 1954 1/2 are close. The grille is different, and instead of a two piece windsheild they have a solid windsheild. Here is a pic of a 54 we have. http://memimage.cardomain.net/member_images/6/web/2142000-2142999/2142496_2.jpg
