The first set I got for my 83 I bought online, but then I needed a custom line after converting the rear master cylinder to an 1800 mc. Low and behold I found a hydraulic line shop a couple miles away. They made the line for $40 to my custom requirement with the 2 ends to match while I waited. Worth a search for a local shop.
There are a few shops in the Phoenix Metro area that'll make up custom lines for you - while you wait! Prices ALWAYS beat the online ones from major suppliers. It'd be worth checking out to see if there are any in your area.
If you can't find a local shop, I'd go with HEL. Had them on the rear of my 81. Worked in the stock configuration and also the modified configuration it ended in... 1800 MC and 1200 caliper.
I bought Goodridge ends and line from https://shop.revivalcycles.com/motorcycle-parts/ and made my own upper front line as I have much lower bars on it than stock. Really pleased with it, and the line is very reasonable but the ends are quite pricey (~$20 US each).
