65/66 Single/Dual Master Cylinder?

Drifting
I converted my manual-brake '66 coupe several years ago with a kit I got from one of the big suppliers. Possibly ZIP or Paragon -- don't remember so good no more. It included a '67 style dual master cylinder, new lines for the front and rear, a couple of junction blocks, and the '67 style "proportioning valve" that everyone knows is not a proportioning valve. I didn't use it, I ran the lines directly to the master cylinder, but I did use the rest of the parts. I haven't looked back -- the brakes work great and I have the extra confidence of the dual system.
