you could look at what classic tube has to offer. i did a quick search on their website for a 73 240z model. here's the link.

i worked with them last year and provided the following to update their database; series 1 & 2 240z, 280z both early and late models-all brake, fuel & vapor lines [even the short hard lines that are on the outboard end of the brake flex lines]. they have [pardon my technical ignorance] a scanner that pulls the x, y & z axis from the lines, converts it into some program, they then feed the info to a cnc bender, it makes the lines, they compare again with the scanner the new vs. old line and make any necessary corrections. all stainless but you can order them in a 'regular' steel line as well. in addition they carry braided flex lines for our z's as well. since they have the fuel line info they can make them to pretty much any diameter you specify.
hope this helps.
