The 59A series have a different starter ring and it's placed differently. 8BA family flywheels mostly have drillings for the 9.5 inch Long type clutch with exception to station wagons, police cars, and trucks but the flywheels can be redrilled for any size clutch. Mercury cars used the Borg & Beck 10-inch clutch so they are different than Ford. Also keep in mind that the 8BA family began in 1948 with the first bonus built trucks while the cars were still 59A series engines. The 8BA car type flywheels are still out there.
