As most of you are probably aware by now, during the early morning hours of Sept. 2nd Nisonger’s facility was buried under 6’ of water as Hurricane Ida passed through the New York area. A substantial portion of our irreplaceable repair parts inventory along with numerous pieces of Test Equipment were damaged or destroyed. After lengthy consideration, we do not feel that we will be able to provide the level of repair and restoration service going forward for which we have become so well-known and respected, thus:

Effective October 15th, Nisonger Instruments will devote its full efforts to the Sale of Classic Smiths & Smiths OEM Replacement Gaugers for the AC/Shelby Cobra’s & GT40’s. Pease note that the GT40 range has been newly expanded to include 270° Sweep Electric Water and Oil Temp Gauges which eliminate the troublesome/fragile Capillary Tubes used by their mechanical counterparts plus a 270° Sweep Electric Oil Press. Gauge which eliminates the necessity of the lengthy Oil Press. Line required by its mechanical counterpart.

The Series I E-Type Amps, Fuel, Temp & Oil Pressure Gauges are exact replacements for the original Gauges utilizing the original Graphics and are fitted with correct OEM Black Full V Bezels.
