Don't use a resistor. You can order a properly calibrated sender from Lectric Limited for about $20, or you can get a Wells TU5 from NAPA or Autozone for about $6. The later has no markings, but is otherwise identical. :auto:

Re: temp guage (CRAIG CARR)
i had the same problem (1960). tried 4 different senders and sent gauge to be calibrated 3 times. still read too hot. Problem solved with an In line resistor. Corvette Central has a variable resistor in catalog. i think it's 20 bucks. It is accurate in the hot side, where it is needed. check with an IR gun. good luck

Re: temp guage (ptuner)
CRAIG CARR,
I agree with 62fuelie that you shouldn’t really use the resistor method. Yes, the resistor method will “resolve” the problem but, it also reduces the range of accuracy and I think that it only covers up the problem.
I know that you stated that it reads 20 degrees hotter than actual but you need to ensure for yourself that the actual temperature is positively correct (you could have a problem with the cooling system). Anyway, you may want to do a search of the archives on this subject. Many people have submitted great information on this subject.
Also, I had the same problem on my ’63 and the TU5 from Autozone did the trick.
Good Luck,
Gary

Re: temp guage (CRAIG CARR)
From all reports, that fix works about 98% of the time. Be sure not to use thread sealant on the threads, or if you must to seal it, use at the bottom of the threads only. It HAS to make good electrical contact. :auto:
