http://www.topsonline.com/inde...05000 or you can source one from ebay:

As your your 5-speed, I would check local junk yards or local craig's list. You can find them on here in the classified section but shipping is a bit much because of the weight. Use the search button...read up on everything...know what your looking for...it's better to source the parts all at once then to "piece mill" them together.
Hope this helps! And welcome again!
PS - Post up some pictures of your ride before the "Picture Police" gets you .
