I am having a hard time finding a big bore master cylinder for my manual front disc/rear drum Duster. In another post, these master cylinders were recommended, "Raybestos MC36338, a NAPA United 36338, or a Bendix 11516," but I am not sure if they are large or small bore. Can anyone help? Thanks

Why dont you just use the stock manual cylinder for the Duster?....cheap, available, effective

Need a more specific question. What means "big bore"? What size do you have in mind? What are you hoping to achieve?

Too many people who were born on third base actually believe they've hit a triple.

There are at least 4 different bore sizes available at the moment. I just bought a complete selection of master cylinders from DoctorDiff. I got one of each size available just so I can tune different brake systems. Smallest is 15/16 and the largest is 1 1/8.
