have you posted a wanted ad for the gauge? surely someone is parting one of these cars on this forum and has the part as a replacement - the whole gauge unit that is. for the 20 bucks or whatever it's going to cost for the used temp gauge you'd be done. it's fine to try fixing the gauge with a resistor but it's also a whole lot easier to swap in a good used unit and go on to frying bigger fish.
