Can someone give me a source for cooper-robertshaw thermostats in Montana, especially the Billings area? I tried the Ford dealer and I got the motorcraft style, but it is the wrong one. Thanks for your help.
I've had good luck with Stant also, but I need to find one made specifically for the 400 motor that has the skirt on the bottom to close the bypass when the thermostat opens up. I even ordered one from the ford dealer for my specific year and engine, but it also did not have the skirt. People on the 335 engine forum directed me to the Cooper-Robertshaw Thermostat.
