Hello Chrysler friends: I saw a 63' 300 J for sale on a web site. The seller lists the car with the VIN number as 8433 159480. I am just curious because I am not sure if in fact this is a 300 J, or if it is a 300 sports series. (I would like to try to purchase it, if it is a letter car) Could anyone out there give me some direction or information, please? Also, is there a way of knowing what the numbers mean, for instance, which production number was this particular one (from the total 400 built that year), or any other features? Thank you in advance!!! I appreciate your help and kindness. Dee [Non-text portions of this message have been removed]
