I had a stock set for my 78 CB550 that I wanted to have replicated in SS braid. I tried for a few days to track them down to try and get an answer as to whether I can drop off the stock setup somewhere to be replicated. Never did work out. I ended up calling Pro6, dropped em off same day, and picked them up a few days later. Was reasonable for what I asked for. Not particularly cheap, but at the same time, you only get one chance to cheap out on brake components, so whatever.
Moral of the story: if you don't have the complete specs of what you want and/or you can't fit it into their web-form (for example if you want to do something like I did) it may not be as simple to do. But, the prices cant be beat if your ask is simple.
