Correct disc brake master cylinders for 70-72 Cultass/442

I have been trying to figure out what is correct for the 70, 71, 72 disc brake master cylinders for a few months now. Maybe some of you may know what is correct for each year. My intention is to have the correct casting number and bore size for each of the 3 years. Pictures would be great also. The following is the information that I have found and think is correct.

1970 Power disc and manual disc use the same master cylinder.
"EB" code 5470409 casting with side bleeders for power and manual disc brakes, single bail, rectangle style, 1 1/8 bore.

1971 Power disc?
1971 Manual disc?

1972 Power disc?
1972 Manual disc
Top held in place with 2 bails


Thanks for any information you can provide.
