I know the 83-84R is VERY tough to find, but I have a friend who is an old timer retired machinist that needs stuff to do. He and I were kicking the idea around the other day of manufacturing swingarm bolts for old bikes/trikes/etc. Of course, I would need samples for a pattern. I have an 83 R one. Any other ones so hard to get? Anyone need an 83-84 one??
