proportioning valve questions

Ok, I'm going through the same thing with my 68 Dart right now and my conversion kit showed up with a proportioning valve suspended right underneath the new master cylinder. I no longer need that splitter/prop valve thingy pictured in post #4 right? Essentially the new prop valve will replace that stock one bolted inside the fender right? I'm having major problems getting the old lines out of that splitter so I'm thinking of just cutting the rear line, flaring it, and then plumbing it and the two front lines directly into the prop valve suspended from the new master cylinder. Does anyone have any comments on this idea?
