So in replacing the wheel bearing in the rear wheel of my 1978 CB400A comstar I cam across the rubber dampers under a disintegrated black cover. The dampers are all made of rubber and go in between the lugs the sprockets bolts go into. They are shot, really brittle and falling apart. Anyone know where to get new ones? I found a source on eBay and the seller is in Germany. I've scoured the net trying to find them. Here's the pic. I entertained the idea of making my own using some 80A hardness urethane casting materials. Thoughts?
