Because there were no truly different chassis types other than some wheelbase variations all of full size cars, the body type designations of B, C, E, etc. were not used prior to 1960. Each year had only a letter designation for all MoPar cars built in that year. Thus, for example, the 1957 model year for Imperial, Chrysler, DeSoto, Dodge and Plymouth were all "K" models (not to be confused with "K-cars" of later years!). Now '57 is my year of specialty but from assorted paperwork, I have, I do know for certain that 1958 were all "L" models and I think I have support paperwork indicating 1956 were in fact "J" models. The progression here is obvious. I do not know if the '55 model year was called "I" because of its confusion with the letter 1 (one). I am relatively certain that the '59 model year were all "M" models. So how or when was this model designation used? I think if you were a parts counter man in this era, you may have been aware of factory parts sheets that occassionally would reference the model year, such a a page I have for "K Series Exhaust Parts for Sports Cars" which charts pipes and mufflers for Furys, D-500s, Adventurers and 300s. Or if you worked in corporate offices or someplace like the carburetion lab, you would see plans for the L series year or similar. It was not a popular designation that a salesman or mechanic would even be aware of. I'm sure I could be enlightened further on this subject myself.
