This, by the way, illustrates the only modification I needed to do to make the pipes fit behind the brake reservoir. I thought about simply spacing it out but I couldn't move it enough and still get the nut on fully. Also thought about a longer bolt but the one there is pressed in and wouldn't easily budget. In the end it was easier to bend the bracket and grind off the protruding bit of the bolt. This placed the reservoir right up against the outside edge of the chrome cover. There is a small headshield that was resting on the pipe, which I just bent in slightly. I'm going to put some other material in that space too but I actually don't think it's needed. What's the worst that can happen? No back brake.......so what.
An alternative would be to space out the whole peg rail and get longer bolts, but it seemed a lot of unnecessary effort. Might suit those who don't want to bend anything though.
