All regular Ford & Mercury cars went to the Ford precursor to the 9" in 1952. Wagons & police cars kept the Dana 44 if I remember correctly. As was mentioned Mercury went to an odd ball transmission with the 312. It was a Dana 45. Ford changed to the 9-inch in 1957 due to the larger engines coming on line. Thunderbirds & wagons still used the Dana 44 through 56 at least.
