Kawasaki Forums - 300 case help needed

So since I got my klx300 in a trade 1 year ago there has been a constant oil leak. Its not enough to drop the level by any significant amount. I had always though that it was from the drain bolt since I never had the proper crush washer on it. Today though, I decided to try looking in other areas. Once finally getting a bunch of dirt and grease I noticed an area that had an epoxy like coating over an area. Upon further inspection it became apparent that the case was broken under the epoxy. I was wondering if anyone had any good leads on a right hand case for relatively cheap. The only ones I am currently finding on ebay is about $250. The other thing I was thinking is would a klx250 RH case work. I am not sure about it but comparing the pics side by side I think they are identical.

Any help is appreciated.
