Tom,
You are right, 65/66 Ford vehicles still used the single chamber Master cylinder, I should have check before guessing at the date. Heck, I could have asked you, since you have a '66. Trying to clean up my mess, I got to searching on the 'net for info. Haven't found the definative answer yet, but...check out
http://www.chtopping.com/Home/, this guy has some info on Drum brakes and the Single chamber master cylinder, they'er nick name is the "Fruit Jar", seems to fit. Anyway, thay have done the swap on Mustangs and rod, nothing on Galaxies on the site, but good information.
