I'm cheap....a roll of 3/16" brake line, a double flare set, a hand bender (optional), and some fittings and you're in business. Less than $50.00 and you can make/modify all the lines on your truck.
Double flares are simple to make...follow the directions to the letter and you will quickly become a pro. While you're under there...it's a good time to change out those 50 year old rubber lines as well.
If you've upgraded to a new dual master you'll need to make some significant changes over stock lines anyways. I've yet to see anything but a premium S/S set, that you could use without modification. Hope this helps!
