We now offer a accurate oil pressure sending unit for many Chevrolet vehicles. Sending units have the original-type terminal connection, and resistance (thermistor); resulting in an accurate gauge reading. They screw right into the block and have a dryseal with 1/8 X 27 pipe thread hole (as original). Although these do not have a exact appearance as the original, they are very good replacement. This is for models with Rally Gauges (not dummy lights).
This fits the following 69-72 Chevy Chevelle Nova Camaro el camino with rally gauge instrument cluster & V8 engine
-original 1/8 X 27 NPTF Dryseal , with factory gauges (correct resistance and connection, produces accurate gauge display)
