I finally have my 292 back from the machine shop and I am starting to work on it. The first thing I noticed is the the driver's side head does not have the threaded temp sensor bung installed. Does anyone know of a source for a new one, or alternatively, a different place where I could mount a sensor. This is for a '57 T-Bird and I have a stock cast iron 4 bbl intake, water pump, and heads. There is a port on the driver's side of the water pump that I might be able mount a sensor in, but I'm guessing that is not a very good place for a sensor.

TIA for any leads or ideas.
