Mark: There are two concerns with your front steel brake line. First, if it twisted off it probably is already very corroded and may not seal correctly or may fracture after the repair. Second you need to "double flare" brake lines. You can buy these tools (most people don't own one) and since you move a lot of material during the double flare it is best to do this with new lines. I have replaced lines on cars with the straight sections of lines with the fittings and flares already in place. You can buy several lengths at most auto replacement stores. You can also put two lengths together with a coupling and come very close to the correct length. It may be much easier to install if you run the line half way from each direction and couple them in the middle somewhere under the pan. Once you get into it the job is really easier than it looks and you will enjoy the peace of mind of having new brake lines. I believe that here in the Midwest no one should run a car with steel brake lines that are over 20 years old. They do rust through and fail. Routing the line under the engine may not be a lot of fun and it isn't nearly as exciting as trying to steer a 5000 pound block of steel out of the way of traffic with the brake pedal on the floor. I would not gamble with anything less that factory specifications and practices when dealing with brakes. Good luck. Rolland
