Looking to identify original Supplier for Clutch Slave Master and Brake Master Cylinders 1976 280Z

Howdy, Hoping someone can chime in.

I read several pages of posts, but was only able to find information about the 240Z cars.

I am looking to replace the After Market Clutch and Brake Master Cylinders with factory correct parts for my 76 (9/75) 280Z.  I think the clutch slave for my year was manufactured by Nabco Japan?  Can anyone help me confirm this?

As for the Brake Master Cylinder, is it Tokico or Nabco?  I know they used different manufacturers and it is unclear what years the transitions occurred in.  Trying to get in the ballpark, so to speak.

Any help is appreciated.

Thank you!
