Cheapest place I have found on-line for copper/nickel brake line is tooltopia.com. They have a better price then even the Napa dealer can get it for, as well as brake tools. Line is cheap compared to the labor, take your time stay focused and $100 worth of material can easily be a $600 to $1,000 finished product. Well worth the effort, do it right and you'll wish they were on the outside of the car for everyone to see.
