65 Valiant 1 to 2 port mast cyl conversion

I was going to put a 2 port master cylinder on my 65 Plymouth Valiant 4 door. Would the master cylinder from a 67 Valiant, non-power drums work? What all do I need to change to make a successful conversion? I know I need a junction block. I think they sell them at Year One. Is there any particular year/model I can purchase the lines that will fit right up? Will there have to be any mods to the brake pedal?

The '67 will work perfectly. Just use the '67 proportioning valve as well as the '67 pushrod which attaches to the pedal.
