Where can I actually get a 1" Master Cylinder?

This is what happened
I picked up an ITR 1" Booster / Master Cylinder, so I sent imy car to my mechanic to install it, nightmare began. He took off the booster and MC from my SIR to replace with the ITR. After installed the booster, he realized the MC requires a 10mm fitting and another 12mm fitting. "Assuming Stock is 10mm x 2 for the steel line."

First question. What car did this MC come from. a non ABS? no clue

after swapping the 12mm fitting to one of the steel line, we installed the MC in place. Therefore, one 10mm and a 12mm now. After installation, including bleeding the brakelines and brand new brake fluid. I jumped into the car and test the new braking response, everytime I tried to stop the car. I had to press it all the way to the bottom, Mechanic assuming the MC is no good. explaining some valve in the MC won't close properly which I don't really get it.

Second question. Where can I get a new 1" MC. Will a part store provide them as well? If I get a new MC. Will the new MC able to bot to the booster directly?

Appreciate.
