If you can afford it, I would purchase a stainless steel pre-bent set. $200, fits perfect, never rust again. Being that you live in PA.
If one could find decent brake line in an auto parts store, mabey I wouldn't be so fast on the stainless, but living in the rustbelt, auto store lines can rust through in as little as a year. Believe me, I know. I did the lines on my '86 with the cheapy auto store lines, I even shopped around to find them painted. a year a couple months later, one burst. Rusted clean through. The OEM steel lines lasted 20 years, the steel auto store lines, 1. I think the OEM's were at least galenized or treated or something, but I've never had good luck with an auto store brake line here in MI. I've used many of them when I was poor, on crappy cars I had when I was younger, and would replace several a few times over a few years. It was always a chore.
$200, a stainless steel set, never think about it again. Plus they are pre-bent, flared, ready to install.
YOu can get from many places, I would recommend

I've bought 2 sets from them, for the K5 (which isn't done yet), and my '865 C10 daily driver, both installed perfectly. I've also bought brake cables from them, had them custom made for same price as ones they already have a template for. Great people to work with, they know their brake stuff. Well worth the dough if you ask me.

also sells.
If you do go the DIY way, make sure to get a good double-flaring tool, the cheap ones hack up the end of the line and that's not something you want compromised.
