3406 is in need of a new rubber bellows for the cabin side of the clutch master cylinder. Early style without the effort reduction linkage.
Was supplied with a new master for a later car with the reduction linkage. Told to swap the pushrods and it should work fine. I believe it will be just fine, but the rubber boots are not interchangeable.
Does anyone know where to source a proper bellows for the early cars?
If I can't find the right one, I suppose I could use DOT 5 silicone fluid in the clutch hydraulic circuit and run without one. That would limit the tendency to absorb moisture at the back of the m/c bore. Grit and dust might be a problem.
