from the 20,s chrysler had a habit of introducing models instead of a specific model-year---a model may last 18 months and not be related to the begining of a year or the end---for that reason grill shells/headlights/suicide hinges are all over the place----yeah yeah i know a sales brochure may show something new in the 1928 series but it may have been in production since last june---it always will cause consternation among those that feel it must show some order....bob
