Does anyone have an image of how the rear lines run out of the proportioning valve? Both of ours run forward, the right hand one is easy enough, but the left hand runs through the centre lower chassis brace from one side to the other. I'm certain it's had pipes made with the engine still fitted.
Looking round the car, it looks like it should come out the valve, back towards the front of the car, then round to the left hand? I've attached a couple of crude drawings of what I have, and how I feel it was.
