Mark is correct. Its just a japanese brake line vs north american line. But the fitting is 10mm since japanese crap is metric 😉

Lenght wise, I think I got a 20’’ for the long/drive side and a 8’’ for the short line on the passenger side. Any longer and you’d have to cut and re-flare the line or bend/loop it around until you use up the extra length etc.
