gauge voltage limiters

the difference between a rally gauge and a 64 valiant is night and day , you are going to need to perform surgery on your gas gauge if you are going to install a new regulator , it isn't hard to do but it is very hard to do without destroying the wafer backing that the 3 terminals and the rest of the bits are mounted to . The old regulator bits must be removed by cutting the internal bimetallic bit out . Ben aka DemonIVR has posted how to do this in the past but unfortunately he no longer sells his product or reworks the gauges so you will have to search the internet for the outfit he wholesales to , they have the info posted on how to install the Demon IVR .
