Hey bike riders and repairers, I need the outer limb(?) of a suntour cyclone m2 derailleur. I took a quick hack at e bay but didn't see an m2. What are the chances I could find just the part and skip buying the whole derailleur. It's just held on by 2 screws. I could post a picture easy...

Anyone else own one? Started the project a long time ago but other projects got in the way. Now I can ride to work again I've blown the dust off and started back up. I've got some serious derailleur issues and not sure where to acquire a replacement.
