Can anybody ID this Master Cylinder?

God Bless ya Mattax,
Such a well articulated and thorough answer.

Though I had not yet searched for a rebuild kit for my existing MC, I did a search on RockAuto for the MC36406 mentioned in another older Abody thread I've since lost but came up with this but the specs didn't elude to the piston bore size. Then in a roundabout way I found this invaluable interchange tool on the Raybestos site:

Raybestos: Interchange

On the interchange I was able to search for my existing OEM MC #3461187 and sure enough their replacement MC's listed 1.031" bore

Shown below in the last image The MC36406 listed a .938" bore and oddly enough they both reference 73-75 Abodies in the fitment guide, if I can get a better pedal feel and obviously still get the car stopped this would be a win for me.

*Update...$52.79 for the Raybestos on Rock Auto, on a whim I called my local Autozone and inquired about it...they have a Brakesbest unit with the .938 bore for $39.99 comes outta Oklahoma City and should be here local in TX tomorrow.

Since i'm going thru the calipers and rear wheel cylinders guess I should have figured out all that stuff too so I can have new boot's and seals, (possibly pistons, pads, shoes) ....uggg it's a labor of love.
