    They are double flare like brake lines. If the fitting on the line is cross threaded, all you have to do is buy a small section of pre-flare brake line. Use a tubing cutter, cut it in half. Cut the end off your old line. Use good high quality rubber transmission line and clamps to connect the new section to the original lines. If the fitting in the rad is cross threaded, use a tap packed with grease to recut the threads.
