Single to dual master cylinder on 64 Dart - What do I need??

Here is what I did, I got a MC from a 67 Barracuda then I got new lines from the MC to the diverter valve for the front brakes I pluged the back brake hole from at the diverter valve and ran another line from the MC to the back line for the brakes. I found the information to do this on slant 6 forum.
