If I remember correctly, the Spiegel brake lines come with a little blue 2 piece plastic gizmo that you can put around the end of the line and clamp it in a vice. Then you use a wrench to turn the banjo end to the same alignment as your stock line.
The angle of the banjo portion may be slightly different from the stock, but it's no big deal once you get the ends turned to match the stock lines.
