Dual Master Cylinder brake lines?

I did a brake swap on my 65 Barracuda, but I had a 73 Dart parts car and a 73 340 dart sport. I swapped everything, spindles, disc brakes, distribution block. I picked up an aluminum 2 bolt dual mater cylinder and adapter plate from Dr. Diff. I even swapped the 8 1/4 rear with 3.23 gears and 340 leaf springs. Everything just bolted in. Now I have big bolt pattern and the car stops pretty decent.
