Sorry I can't help but I must say that this is the one area where KTM has dropped the ball. I did a little damage to my 98 200 in which one case required replacement and they won't sell you just the one side. Hence the unreal price.
Depending on the amount of the damage you might want to look into someone qualified enough to weld them up. When I had the problem I got the case welded and it was perfect after that. Be careful I can't remember if the cases are magnesium or not and it makes a big difference when it comes to welding. Good luck
