The only part that was a challenge was finding the right flaring tool. The custom kit just gives you more options. As far as the length, Russell lines or Goodridge lines can be custom ordered on their webpage or at J P cycles. I used a pre-made line upfront and a custom 'through the frame' for the rear. I used the stock Triumph calipers and combined the front with a PM master cylinder and the rear with XOXOPRODX forward controls. I am very happy with the performance of both set-ups.
