J&P Cycles will have the brake line and fittings, measure what you have and add the difference for length. You can get any look and color brake line you want and fittings to go with it. They have AN3 fittings that you need for brakes to be safe and legal. The banjo fittings are 10mm and available in different angles. Do same with cables, measure yours and add the difference. Barnett can make them for you and there are others that can too. Used to be able to buy endless cables and solder your own but haven't seen those in a while.

I learned all I need to know about life by killing smart people and eating their brains.
