OK, I just found your post there...
OK, then two more sources...
A. New Hope Guitar Traders (a/k/a The Guild Guy) at http://www.guildguy.com/
Jay's website says he has some parts- please call, fax, or e-mail for specific request. Nice guy (I've bought a couple of things from him, including my Pilot) and very knowledgeable regarding Guilds.
B. Hans Moust- he hangs out on Lets Talk Guild, and he's the man who wrote the book on Guild- litteraly- he wrote a great history of Guild. Plus he's acquired quite a few parts for Guilds. I just got a replacement pickup from him that's period correct for my Starfire 4 guitar for substantially less than having the stock pickup rewound by anyone- and that included shipping from the Netherlands. You can find Hans' e-mail over at LTG.
Good luck, this can be very frustrating!
