Any advice on getting the pin out? The manual just says 'extract the pin', which suggests there's a special tool? I'd really rather not remove it as it's fine but I have to replace the bushings on the adjacent link and the bolt is facing the driveshaft, so it's not coming out even if I get it unscrewed. I have a spare pin so I don't really care if I trash the one in there. Also, there seems to be some sort of pin on top that inserts into the pin shown on the diagram but there's no reference to it in the drawing or ass/disass instructions.
