    Somebody please correct me if I am wrong
    I’m thinking since the prop shaft is threaded- it a 1956 and under
    I’m thinking since it takes a long bolt in the rear-its a 1955 and above
    So its a 1955 or 1956
    I’m also thinking that inside it has a short pinion gear
    I believe 1957 was the first year of the longer pinion gear
    Just my opinion
