No pics, but the front line goes down my upper control arm to a Y on top of the axle tube. That Y is secured via a 3/8"bolt welded to the tube. Then it splits to each caliper.
The rear is similar but having cutting brakes makes the plumbing a bit different. But typically I just run the rear supply hard line inside the frame to a flexible hose that drops down to the axle. Secure it just like the front is via a bolt welded to the tube. Then hard lines on top of the axle tube to the caliper flex hoses.
To secure to the axle tube, I usually just weld a thin (1/8") piece of 1" x 1" plate and then bend it over the line.
