Autozone should have the sensor you need.
I would not take any chances w/ the thermo, replace it. My car takes almost 3 miles of driving to start to show an temp rise. Around 10 minutes the gauge will read normal temp. This condition only exists on cold mornings in my 250k coupe (yes it has a new HONDA thermostat). My sedan gets to operating temp rather quickly, but that engine only has around 50k.
I ran into the same situation with an aftermarket radiator. I had to use a nissan type radiator cap. It fit perfectly, just make sure you get the right pressure the cap was calibrated for.
