The late 1951 Mercury with the T-259 type transmission has a full cast iron bell housing with the removable cover on the bottom but it was the only one to still use the rotating fork type throw out control. The earlier ones had half the bell on the transmission housing like the early Fords had and the half bell stamped steel clutch housing.

In 1952 Ford & Mercury finally started using the same cast iron full bell housing but the Mercury still used a Borg & Beck clutch. The 49 thru early 51 Mercury transmission will bolt right up to a 59A and even has the right spline for the Long style 10-inch clutch. The only problem is that it won't fit an early or a late 1/2-ton 1941 pickup frame very well.
