I don't think that's it, at least not the factory one. $79 is way to high for what the factory one would be. But thanks anyway.
That is the correct part. Thanks a lot TooSixy!! Yea i will call them anyway, maybe they'll send me two. My left side is the one which fell out sometime.These are the ones. Make sure you buy the right parts because VP9 and VP40 parts are different. Again, I would call HKCS first and tell them what happened. They may send you free replacements.
