Rob, the job is fairly easy. takes about an hour or so. Not as bad if you understand that pulling the inner fender will make it easy on either side, but not necessary. You can cut the old line off, and put a socket on the nut. That will get it out of the box, then going through the wheel well will give you a better angle to install the new one than under the hood. Autozone can get Dorman replacements. I have done them a couple times and found a system that works great if replacing both lines.
The duralast lines are made by dorman.
