Inline Tube and Classic Lines, I think, both have them. Or you can go to Pep Boys, Kragen, etc and but the lines and bend them up yourself. It's not too hard. I just finished doing my Fairlane.
i just did mine from the prop valve to the wheel cylinders, i just bought the line from summit and made my own, if you have time and knowledge its not that hard, also put a new rubber line between frame and rear from napa. Some bends are tricky and a PITA
