You will have to fabricate your own brake line. Use a flex line from the caliper to a T fitting with a hydraulic stop light switch nerr the rear of the transmission and then a hard line forward to the master cylinder. I have used universal hard line from an automotive parts store and bend it as needed. I run it inboard of the frame being sure to keep it above the bottom of the frame, the scrub line, so as not to drag when up on a lift, or when riding over road surface obstructions, like curbs or speed bumps. Also be sure to allow about 1/2", 13 mm, clearance around the exhaust.
The MC pictured has a 3/4" bore, the GMA 5/8" MC works a little better and is what I use. The iron MC will be OK BUT you will need to open it up and REMOVE the hat shaped check valve to use with your disc caliper, otherwise the brake pads/pistons will not retract properly because that valve holds residual pressure in the hydraulic system. It is for drum brakes only....
