temperature sender

[David Councill <dcouncil@imt.net>]

Where does one get the temperature sender repaired or replaced on the early 
60s B? I'm not getting any temperature reading on a 65B and my trusty Moss 
catalog shows that the gauge, sender, and cable are all one part. Previous 
list posts indicate that the temperature sender uses a fluid expansion 
principle through alcohol or ammonia, but no definitive info on where/how 
to fix it when it stops working.
