Wanted:

[8ball]

I need the string locking bolts for a Kahler Spyder trem. Will buy entire bridge or guitar.

For any kind of parts, try looking at the manufactorer's site. I don't know if kahler has a site or not. Search for the tremolo you have in a search engine like Google (www.google.com). Ebay may also be a good place to look.
