Well Napa has the above mentioned booster and master cylinder as a unit. It lists the Booster Diaphram Diameter as 10 3/4". I'm not sure if that includes the thickness of the sheetmetal that encapsulates the Diaphram. Probably call it 12" in diameter to be safe for a little extra room. Anyone know of a good prop valve to use or the application to look for?
