Fitment Guarantee & Installation Disclaimer

At Anvil Auto, we are committed to manufacturing high-quality aftermarket automotive components using modern engineering, CAD design, precision tooling, and rigorous quality control processes. Every product is designed to provide the best possible fit for its intended application.

Classic & Vintage Vehicles

For classic vehicles, a perfect, bolt-on fit cannot be guaranteed for every individual vehicle.

Vehicles were produced with manufacturing tolerances that were significantly greater than those of modern vehicles. As a result, no two vehicles left the factory exactly alike. Over the course of decades, additional variations may result from collision repairs, rust repair, replacement body panels, aftermarket modifications, chassis flex, worn body mounts, previous restorations, and normal vehicle aging.

These accumulated variations mean that even the highest-quality aftermarket parts may require minor fitting, adjustment, shimming, trimming, elongating mounting holes, or other installation modifications to achieve the desired fit and panel alignment. This is considered a normal and expected part of restoring or modifying classic vehicles and is common throughout the automotive restoration and performance industry.

Our parts are manufactured to fit vehicles that are in factory specifications and dimensions. Because we cannot inspect or verify the condition or dimensional accuracy of every individual vehicle, we cannot guarantee identical fitment across all applications.

Modern Vehicles

For late-model vehicles, our products are engineered using OEM reference data, CAD modeling, and precision manufacturing processes to closely match factory specifications.

While modern vehicles are built with much tighter production tolerances than classic vehicles, fitment can still be affected by factors outside of our control, including:

  • Previous collision damage or structural repairs

  • Aftermarket body panels or replacement components

  • Suspension or chassis modifications

  • Damaged or worn mounting points

  • Vehicle manufacturing tolerances

  • Installation technique or component alignment

Most modern vehicle applications should require little to no modification when installed on an unmodified vehicle that remains within factory specifications. However, minor adjustment or alignment during installation may still be necessary, particularly for body panels, aerodynamic components, composite parts, and performance accessories.

Our Fitment Commitment

We stand behind the quality, accuracy, and craftsmanship of every product we manufacture. Our components are produced to our established design and manufacturing tolerances and are intended to fit vehicles that remain within factory specifications.

If you believe a product has a manufacturing defect or falls outside of our production tolerances, please contact our technical support team before modifying or installing the part. We will work with you to evaluate the concern and determine whether it is related to the product or to variations in the vehicle.

Because every vehicle is unique, we cannot guarantee identical fitment on every application. Professional installation and minor fitting or adjustment may be required depending on the condition and history of the vehicle.

Our goal is to manufacture parts that meet the highest standards of quality and fitment while providing the best possible installation experience for every customer.
