Bill: The body designations such as "A", B", "C", "D", "E", "F", "J", "M", "R", "Y" etc. didn't come along until later. You might like to refer to this: http://www.nationalmoparts.com/v_id.html for more detailed info. You might also visit Allpar at: http://www.allpar.com/ for some great information and history on the entire Mopar line. They also have some great articles on the different engine designations over the years. The pre 1965 Chryslers were officially just referred to as the big car platform. Most people put the early Chryslers into the "C" body designation. Basically, the "A" bodies were the smallest, then the "B" bodies were the mid-sized cars and then the "C" bodies were the larger sized cars. I hope this explains it somewhat.
