Replacing brake lines

[dzwestwindsor]

The brake lines on my truck are fairly rusty and I want to replace them. LMC has pre-bent lines for sale, but I want to make my own.

I have a 1971 C20 with power disc brakes in the front. Before I start ripping out the old lines I want to have everything ready. I've never done this before, so I need some pointers.

Are the steel lines for my truck 1/4"? Can I just get a roll of these: http://shop.advanceautoparts.com/p/p...08%7CL3*15690#

and then double flare them/bend/cut them?

I'm mostly concerned about the connections- where do I get the brass fittings that screw into the MC and such, and how do I know which ones to get? I can't seem to find them on auto parts websites.

I'd appreciate any help, thanks.
