Will a 400ex swing arm match-up on a 350x frame?

 

or do they make after market swing arms for the 350x ????

 

I'm not aware of any company that makes aftermarket swingarms for the 350x. I think we're just limited to getting our swingarms fabbed by a machine shop for extra length. The 400ex swingarm would be great if it would bolt up but i'm thinkin it might be too wide (correct me if i'm wrong).
