Rear brake line help

Thank you guys for the advice. I have some experience double flaring because I re-did the lines that go from the "T" to each drum wheel cylinder. I just wasn't aware if I could do the same to this line because of the spring like external protector. I would never try to cut costs on brakes or anything critical but it would be such a job to reroute this rear brake line from the front to the rear "T". If I were to buy the line, is this the right one? Thanks guys
