You can go to O'reilly's and get the lines off of a YJ. They are longer and are only like $30-40 for all of them. I don't remember really. Go to madxj.com and look at the brake section. There is a thing about braided breaking.
for the front get the O'Reilly # BH38620 and BH38621 (these are chevy p/u lines and are cheaper then yj lines) on the rear use one from a 96 Dodge Dakota. I am at 4.5 or so and have plenty of slack at full droop, both front and rear.

They all fit fine. On the fronts depending on your back spacing you'll need to put a small bend in the line to clear your wheels. On the line mount I opened it just a bit to move it all the way up and mounted to the body in the factory location. When you see the line you'll understand better what I'm talking about. This is what I've run for 2 years so far and no problems.
