I have an mc21 swinger that I bought to put on my rz500 but decided to do something else. It comes with the chain adjusters, chain guide and one pivit point spacer. Its also partially polished. This is how it came when I bought it. I'm looking for $250.00 for it and I can polish it for an additional $100.00. I can send pics of the swinger and of some of my polishing work to anyone interested.
