I decided against installing any of my previous brake components so I did some research on braking systems and lines.  I wanted to keep the cleanest look possible on my firewall so I decided to forgo a canister type vacuum booster and went with a Buick Powermaster electric motor driven booster assembly.  Jury will be out on that until I have quite a few miles on the road.  The Net is full of posts about the reliability of the system but a mechanic I have great trust in swears by them and has one on his 600 hp Camero. I installed the motor on my frame rail below the master cylinder.  I used a rubber sheeted steel band pipe clamp (plumbing supplies) to attach it to the frame rail.
I was planning on using steel brake lines (hard to work with), then thought about stainless steel brake lines (even harder to work with) when my internet research discovered a seldom used line made of a nickel/copper alloy called Cunifer.  You can read more about the material at this link: Cunifer Brake Lines
I purchased my line from a very helpful and easy to work with outfit called Federal Hill Trading company, or FedHill for short. Here is their link: FedHill  I used both 3/16" and 1/4" lines.  FedHill will lend you a excellent flaring tool that allowed me to install my own flare nuts and do my flaring in my garage.  There is a $25 a week rental charge on the tool and they are very generous on their definition of a week - its more like 10 days.  After practicing one or two times, I was ready to make the real things. It was sooo easy.  I was able to hand form the 1/4" cunifer (try that with steel or stainless steel) and I only needed a little help from a tube bender on the larger line (I also used it for fuel lines - upcoming post).  Cunifer has a nice look to it as well and can be polished with just a rag.
I installed a GM combination valve since I kept my rear brake drums after deciding I didn't want to spend a grand converting them to disc.  I placed that up front hidden out of the way on a cross-member. I never liked seeing those things dangling underneath the brake booster.  This photo is more to show the cunifer line than the combo-valve, followed by a photo of the installed Powermaster.
