1971 Ford Bronco VIN Decoder

Last Updated February 23, 2024 | Kevin Brent

Restoring your vintage '71 Bronco can be quite a challenge when it comes to finding the right components. It's important to know exactly what original parts were included with your '71 Bronco model. Luckily, you can get this info by decoding the VIN and data plate of your 1971 Bronco. A Bronco VIN decoder can simplify the process and find the necessary components for your restoration project.

Locate important details like the series, body style, transmission, axle ratio, and color of your '71 Bronco. The vehicle's VIN will also provide you with the engine code, which can be useful for restoring your Bronco to its original condition and also recognizing any aftermarket components that may have been added by previous owners.

1971 Bronco VIN Number Location

If you're trying to find the VIN of your 1971 Bronco, the easiest place to look is on the frame rail located beneath the engine, just before the firewall. Reading the VIN from the engine bay can be difficult, especially with the engine setup. If you can't read the VIN stamp from the engine bay, we suggest turning the wheel as far right as possible and using a camera to take a picture of the VIN from behind the wheel well.

1971 Bronco VIN Plate Location

The full VIN plate is inside the face of the glove compartment door. It includes codes containing your '70 Bronco's production information. The top line of the data plate displays the following code categories: color, type, body, transmission, axle, and DSO.
