Where ever you may find one, make sure and test it with a multimeter and some hot water and a known accurate thermometer to make sure the new sending unit functions per the design specs needed for your application. I bought a perfect looking reproduction one once that was so far off my factory gauge worked wildly wrong. It caused me a great deal of stress and concern until I determined via a reliable secondary gauge that the engine temps were just fine. I tossed the reproduction and found a good used original I cleaned up and installed, everything works just fine now.
My point is, when you do get one it might or might not work as it should, check it first so if and when you see weird functions from your dash light or gauge it won't be a surprise or cause any panic.
