I have ordered the swing arm caps and front sprocket cover, and will update when verified.

I installed the 2008+ sprocket cover today. It fits well. I'm not sure it is a 100% fit, but at least 95%. The top bolt, closest to the frame wanted to pull the top in a bit too much. When I have time, and better light, I'll inspect closer. But, as a direct bolt on - as-is, I say it is fine.
