First call the RAM MAN and talk to him. He can teach you what you need to know to do this, he's an expert on old Mopar beake systems.
He can hook you up with the proper master cylinder, then a prop valve.

There is an option to use a "splitter block" after the old prop valve, but I went with the 67 style system when converting my 66 Valiant to dual reservoir and then ran all stock type lines from Fine Lines.
Then go to fine lines and get some lines to hook everything back up...
