10" Drum Brake Hard Line Challenge

Call me paranoid, but there is NO WAY I would run a brake line in soft copper. NiCop, sure- but not soft copper.
A quick peek at The Right Stuff and Fine Lines' websites didn't show those lines, but I'd still give each of them a CALL. These places generally have a lot more than they put on their websites, or can make the parts special.
Failing that, get some steel or NiCop line and bend your own, copying the originals. Cut the brackets off the old ones and solder/braze them onto the new ones.
Edit: I misunderstood the pictures- the brackets don't need to be soldered on to the new lines- looks like they mount to the hose fittings. I need to stop looking at things on my phone and stick with the laptop.
