Make them with some nickel copper lines. Easiest thing ever. We make them all the time here.
Without expensive equipment you wouldn't have that we do you can still work with that stuff. As in bend it with your hands. Its great stuff.
Get yourself a cheap flare tool if you're only doing this once.
Trust me....trying to do pre-bent lines with the body on, wiring, steering box and shaft...radiator splash guard, side skirts, vacuum plumbing, more wires, etc. Without bending the "pre bent" lines...trying to fit that shit up in there. LOL..
It's tool throwing time...LOL
Get a roll of the nickel/copper lines, the fittings you need...a cheap flare tool...
Go cat go.
