I bought Goodrich stainless brake lines and mechanic said they wouldn't work. I just went to the shop and he showed me. The Goodrich lines have a 3/16 flare nut whereas the hardline on my stang has what looks like a metric fitting and it is larger so it doesn't even come close to screwing together. Anyone know what the nut dimension size is on the hardline? What SS brake lines have people installed?
