There will be a single hard line for the rear brakes coming along the left side of the chassis from one of the two brake master cylinders. It will tee somewhere on the left side and run to both rear brakes. I started by fabricating the hard line that will run from the left side of the chassis to the right brake fitting. It runs along the left, upper diagonal and across the aft edge of the reinforcing plate to the right, upper diagonal. It then drops down the right, aft diff support before turning forward to reach the fitting.
Here’s a view from the front side of that fitting looking aft. I haven’t added any clamps to this tubing yet, but it will not touch any part of the chassis when I do.
