Master Cylinder

Hey everyone. I have recently completed a drum to disc conversion on my 1968 dodge dart, and i was wondering if anyone has and recommendations on master cylinders. I found one on rockauto that is specified for front discs and rear drums, has anyone else used this? Think it will work fine with an upgrade to my rear drums?

Front wheels have 9in drum ->disc brakes, rears have 10in drums

Any help is appreciated, thanks everyone!
