We had a 74' C60 that had the vaccum 2 speed. If the above ideas don't solve your problem, ours was converted to an electric 2 speed. Our local mechanic did the work a long time ago. I don't believe the conversion was that expensive and worked perfectly. I think he got the parts from a salvage yard.
