New Circuit Boards could provide the solution to your blinking or non-functioning gauges. These GM discontinued 78-82 Corvette Speedometer and Tachometer Circuit Boards and 77-82 Corvette Center Gauge Cluster Circuit Boards with thicker copper circuit paths and bulb contact points are an investment you can afford!
Don't be fooled by cheap imitations that are thinner and will not function correctly. Easy, plug-in installation with provided instructions.
Tech Tip: A pencil eraser works well to clean and brighten the copper contact points on the dash wiring harness connector. While you are working in this area it is wise to replace all of the lamps to provide bright illumination to your finished project. These light bulb kits are available as a complete car set and a bargain compared to a second dis-assembly of the dash area.
