"BRAKE LINES"
It is in the back of AutoZone where they keep the belts, hose and such. I can't remember the correct size, but it's like 14 bucks for a decent amount.
Find out what AN fittings you need, how many, etc..etc. You will want -6 to be your main size. Get yourself a bender, flaring tool, and cutter. Then have someone who is experienced in the field, help you. Summit will carry all the AN fittings that you need.
Make sure you draw out how you want your system to run and figure how many "T's" you'll need, fittings, how your bends will run... blah, blah, blah. And make sure you use a proportioning valve that is NOT for ABS.
I'll try to find out what size line you'll need. But I do not recommend reusing the old lines.
