ZX-9R Engine Case Cover

Hi
Just wondering if anyone out there knows how easy it is to replace the Left Hand Side Engine Case Cover?
Also and probably the first question that should be asked is, is there Engine Case Covers for the 9 (1999)?
If so were are they from and which is the better one or should I just replace it with an original
Cheers
