Nothing was available for the 2nd gen. last year when I was looking. A couple of months ago I noticed that a local store advertised that they could make SS lines.
Last month I had a pair of my front lines remade into stainless steel. I brought them a pair of front lines, and they cut off and reused one end. The other end they had in stock. My store here is a Royal Brass and Hose.
Look around at hydraulic line making stores, and ask if you can get brake lines made. Good luck,
