Maverick Master Cylinder Identification?

How do you tell if you have a ’74 Maverick Master Cylinder for a Granada brake swap? About 2 years ago I picked up a manual front disc master cylinder for a 1974 Maverick. Last summer I bought 10 other Ford style master cylinders from a guy at a swap meet, the 10 for $10. I couldn’t pass on the deal. Some had boxes and some did not. My ’74 was shipped in a plastic bag and a shipping box. Well it got mixed with the other master cylinders and I have no idea which one it is? There are three that look almost identical to each other and appear to look similar to other pictures I have seen of a master cylinder used in a Granada swap. Is there a way to tell which is the ’74 Maverick M/C? None were OEM Ford parts and none of the cast numbers on the body make sense. Is there a bore size 7/8” 15/16, etc…? Or a stroke dimension that I can check?

Thanks,

The Maverick master has a 15/16 bore size. Same as Granada BTW.

The Granda master cylinder will have the ports on the fender side of the casting. If the master cylinder has reservoirs of the same size, they are drum-drum master cylingers. Maybe these two observations will help eliminate a few.
