I am considering replacing the floor shift SM420 4-speed transmission in my 1952 3100 for a column shift 3-speed transmission.
Question: What difference(s) if any, are the 1948-'53 3100 3-speed transmissions VS the 1949-'54 CAR 3-speed transmissions?
The reason for this Question is: A CAR Transmission in good/not abused condition will Probably be easier to find.
