Master cylinder for 1970 disk brake conversion

Hey All - I am still working on my 1970 dart which I have installed a 73 front end with disk brakes. I installed an 8 3/4 out of a chrysler 300 with 11" x 3" drums on the rear, the car is originally a manual brake car. I am hoping for some guidance on how to complete this, any recommendations for master cylinder, proportioning valve etc would be greatly appreciated.
