Cunifer is a brand name for copper nickel. Possibly the best brake like made, follow JHZR2 thread he did a nice job with the products from fedhill.
Ironic, last CuNi line I bought was from same amazon seller and also used the Eastwood 31244 version of that flare tool, very handy for making on-vehicle flares.I just did brake lines for the first time using this tool:

and line from these folks:

You'll have to figure out what fittings you need, but it isn't hard at all with that line/bender.
Me? Lust over tools? Never!All I'm hearing is an excuse to buy the Maddox copy of the Mastercool hydraulic flare kit. Something I've drooled after for a couple decades and still haven't pulled the trigger.
I'm disappointed all -- never pass up an excuse to buy tools. Geesh.
The truck is in the Bay Area in a cool microclimate near San Francisco Bay. While it’s not going to Tahoe or the Sierras, there’s rust on the lines. If the friend won’t spring for the kit, I’ll have him order just the rear lines, I’ll get pre-flared lines and form them for the rest.Since you are in California, road salt doesn't seem to be an issue. If you don't want to make them, I would just buy galvonized premade lines from from your local auto store. You can bend them yourself. If you measure the entire length and use a couple unions to join them. I don't see any reason to get stainless since your originals lasted 33 years.
Stainless is the hardest metal to work. The mild steel of "standard" line is easier, and Nicopp the easiest yet. Beware that brake fluid dripping down your arm is no fun, so have a plan to minimize "switch-overs" from old plumbing to new.
