I am having difficulty finding a replacement thermometer for a Ford Model T motor meter. The thermomter should be about 3.75 to 4 inches, be filled with red fluid, and function (not self destruct) in a range of 10 below to about 225 above Farenheight. None of the usual antique car supply houses seem to stock them. I have read posts telling how to replace them but none telling where to purchase one. I would appreciate any information available in this matter. Thank you.
