I have found it's best to fab new lines. If your flair nuts are still useable, cut the old lines to remove the nuts. You can buy steel line by the foot at NAPA and make your own double flair on the ends. If you need the double flair tool, NAPA sells that also, and then you can also do brake lines. If you need 14mm flair nuts, Classic Tube can send them to you. (ad in off road mag).
