Here are some places to start your search:
* Classic Corvette Parts Suppliers: These specialize in parts for older Corvettes. Examples include:
* Eckler's Corvette: A large and well-known supplier.
* Corvette America: Another major supplier.
* Zip Corvette: Offers a wide selection of parts.
* Online Retailers: Sites like eBay and Amazon might have used or NOS (New Old Stock) speedometers. Be cautious and check seller ratings carefully.
* Specialty Gauge Shops: Some shops specialize in repairing and restoring gauges, and may also sell replacement units.
* Local Auto Parts Stores: While less likely to have a specific part for a '76 Corvette, it's worth checking your local auto parts stores. They might be able to order one for you or recommend a supplier.
Before you buy: Determine if you need a complete replacement speedometer assembly or just the inner workings (the mechanism). Also, note the following:
* Cable-driven or Electronic: 1976 Corvettes used cable-driven speedometers. Make sure you get the correct type.
* Mileage: Does the mileage need to match your car's odometer? Replacement speedometers may come with zeroed mileage. This is a legal consideration depending on your location.
* Gauge Face: The appearance of the gauge face (color, font, etc.) will vary. Choose one that matches your car's original style if that's important.
In short, your best bet is to start by searching the websites of the major Corvette parts suppliers mentioned above, using your Corvette's VIN or as much detail as possible about the car's specifications.
