Probably too late now, but if you can contact Jalli (sorry I don't have # anymore) they will send you a replacement for free (at least they used to about a year ago). If you haven't replaced yet, get the number from your LFS or whoever sold it to you, or have them get it in for you.
Found a # for Jalli on the web, called and they are su8pposed to be sending a parts list. If the it works out I will post the phone #. Thanks again to all
