Master Cylinder Brake Line Connection Question

[69GT]

I'm converting my 69 Dart from manual drum to manual disk brakes. I picked up a set of brakes from a 74 Duster and I also purchased an NOS 74 type prop. valve. What I would like to know is which ports on the master cylinder do the lines from the prop. valve go to? I've been doing a little research on this and I have found articles that say the line from the top port on the prop. valve goes to the front on the master cylinder and the line from the bottom front port of the prop. valve goes to the rear while others I've read say just the opposite.

I found this reference picture in my archives.

Hey just a heads up. When I swapped my 4 wheel drum splitter valve and put in a proportioning valve all my drum brake lines screwed right into the disc brake valve!

some pics for ya. The master lines cannot be switched they won't fit. Threads are different. That diagram above I don't believe matches my pictures. But my eyes are not to good.

Yes the threads are different. It'll only fit the correct way!
