you can also get a solid state IVR (instrument voltage regulator) plugsin place of the stock points type on the back of the dash. the stock gages run on 6 volts, and a vibrating points type regulator dropped the 12 volts to 6 for the gages. problem with these is that as they get older they have a tendency to stick closed pinning the gages, or stick open causing the gage needles to fall. the solid state ones plug n play, and look like original.
