Shocker Washers ?

My favourite bits are the washers with a flange around the hole in the middle so as to provide a sleeve to protect the hole in the mounting bracket. Then if you're lucky there's a protruding piece on the bush which is the right size to go in there, and keep the pin away from contact with the bracket. Last time I changed mine I fitted Konis and they had that sort of arrangement, whereas the ageing Britpart ones I took off had almost worn through their pins. They also came with a diagram showing the cup shaped outer washers with the convex side towards the bush, so that's how I fitted mine.
