    AFAIK the ring lands & grooves and the ring set. The later is preferred, but I'm not sure w/r/t the "female rod in front" etc. oil control thing. If you have a '46 you should be using the later pistons.
    IIRC the 1936-39 EL uses the same ring set (but not pistons) as the 1937-? U/UL, same bore size.
