I'd think twice about the stainless line. I did one truck with it, and while it worked fine and turned out well.. it was a real pain and huge aggravation to flare and bend just right, even with the best tools I could find, and I'm pretty good at flaring, fitting, and bending lines.
I now use copper nickel brake line

Although even if stainless were about free I doubt I ever use it for brake lines again.
