Old bushes knocked out today. They were as Julie described: a sort of Bakelite material, definitely not metal. I concocted a tool to knock them out made of a length of M10 studding. Worked a treat. When it comes time to put the arm back in the frame I’m probably going to need some help. Looking at the parts diagram I don’t recall there being that many spacers and washers etc when I took it apart. Everything that came off was bagged up however,
