Master Cylinder Fittings

Any auto parts store worth it's salt should have the fittings you need. If they don't, try somewhere else. Our NAPA store is one of those places. Experienced car guy counter people. They line up to talk to Barry.

Unfortunately, without a part number, I'm SOL at any of the local auto parts stores. I tried yesterday, and ended up bringing home two tube nuts that won't work.


That kit doesn't have the fittings I need. The later model master cylinders (aluminum with plastic reservoir) uses long 1/2-20 and 9/16-20 tube nuts (photo above). Inline tube does carry them, so I know I can get them, I was just wondering if anyone has a part number for those fittings so I can pick them up locally.
