68 Barracuda front to rear brake line route

Looks like you will have to creative with your brake line. I am sure that someone else here has done it, maybe they will chime in. I have home made square tubing welded in, I am having a flexing issue and was looking at usct for better torque boxes and sub frame connector, that's how I knew about the fuel/brake line issue. Trying to avoid a full roll cage.
So, your probably going to end up with a splice, probably two. Drilling two holes through the sub frame connector, grommets, and making the spliced part of the line, tricky because it will want to be bent in two places at 90°. Stainless is kinda snotty to flare. Haven't layed under my car for alternatives, I'm sure that there are. Take a good look at it!
