I ended up just going with "normal" steel brake lines, napa didnt have anything else according to the parts guy there, and while he was helpful, he wasn't enthusiastic about doing any research.
I picked up two 5 foot section, longest they had and some flare fittings. I may still order a roll of line from someplace and make up one piece lines, but this will work for now at least.
on the upside, if i crush the lines i can replace just the under-body sections rather quickly with it set up this way. Im also looking at maybe perforated drywall edging as a protection plate, so it will drain and ventilate.
The reason for so much concern is because im looking at some performance springs which will lower the car about 2 inches, to just under 4.5 inches clearance once I adjust the rear suspension to match the fronts, car sitsa bit high now.
Ive got one line done, probably do the second today, but they shorted me on fittings so i have to go find some more. Ive also got new clips on the way, and I also scored on a good set of front rotors and calipers for $20.00 from a guy who upgraded to a five lug set up. this is the same car that sat in a mud pit for many years, but shes running great now and im moving onto brakes and some electric issues, and lots of cleanup work...
