Since it seems those with single disc setups are somewhat disadvantaged, I'm offering up my spare master cylinder free to anyone running a single disc setup and planning a twin disc conversion.
It's from a '97 748 and has hoses attached. It doesn't have a lever (NBs had that) and you'll need a reservoir.
Caveats...
You must be a current DSC member You must currently have a single disc setup and be planning a twin disc conversion after this weekend.
Reply in the thread so others can see and U2U me details.
Thanks for the thought TP but Jason had already U2U'd me before posting it here. As I changed mastercylinders on the day I don't think the mastercylinder was part of the problem, so I thanked Jason for his kind offer and suggested there may be someone else more in need of it.
