Help with master cylinder id please

Im looking for a rebuild kit for these. im looking for some direction as to what they came from perhaps. they are a 1 inch bore. they are marked r9 and r19?

 

probably early mustang. like 1965

 

Try 1960-64 Ford and Mercury.

 

They look the same as our 63 Mercury Comet, which Id imagine is the same as early Falcon.

 

Mustang and Falcon might have a smaller bore size.

 

One's the clutch master cylinder and most likely they would have left out the residual check valve in it.

O'Reilly's site shows that a 66 Mustang and several other Fords that year have a fruit jar master cylinder with a one inch bore.
