Griz,
Why not just take this opportunity and switch to the Warn manual hubs. They work MUCH better than the auto hubs. Also, if you ever break a manual hub, Warn will replace it free, including shipping, since they have a lifetime warranty. I just had one replaced, they were very quick about it, no hassle at all.
You can get the manual hubs and conversion kit, shipping included, for $163 from a company in S. Carolina. Someone posted that a month or so ago so if you search manual hubs, you should be able to find all the info.
