I always made my own, best way to get a nice fit. Used to get stuff from Earls supply, when they finally came out with -3, I had to have.!!
From my chrome m/c straight out and into a drilled stem nut to a T under the bottom tree. Then 2 45 degree forged fittings then the line to the calipers....167.00 I think in 78 or so and I had to assemble!!.. nice looking setup, get exactly the curves and arcs you want.
Should mention, if you got duals, might not hurt to pack a block off plug when travelling..one year I broke a line in Sturgis.. cant remember how, and was without brakes for a bit.. finally got one made at an airport.. fat black rubber with greenyyellow fitting on each end!!
Lines do break or get tweaked once in a while or vandalized.. its nice to be able to fix them or shorten brakeline if you change bars or forks..
