It’s the Nicop stuff, nickel/copper mix. It’s legal brake line just has a copper mix.
Thanks for all the feedback, I have a set of xhd springs on the way and a new pinion snubber. Also u bolts since one decided to strip as it came apart. I plan on making spring clamps for the front sections. Need to get it together Tuesday for test hits Wednesday since I’ll be traveling for work until the night before I need to leave for drag week. Have to get it all wrapped up by Thursday.
