    Product Description

    Note on Photos: The images provided are of the actual item you will receive. Please inspect the photos carefully to confirm the condition and specific features of the part. Because these are vintage components, minor surface variations or packaging wear may be present; however, the part pictured is the exact unit being sold.

    A Note on Fitment Accuracy: We manually research and cross-reference our fitment data using vintage manufacturer catalogs. While we strive for 100% accuracy, these decades-old resources—and the humans reading them—can occasionally contain errors. Additionally, these parts may fit other vehicles and years not explicitly listed in our data. To ensure a seamless restoration, we kindly ask that you perform your own due diligence and verify that this specific part number is correct for your application prior to purchase.

    Unbeatable Prices & Expectations

    While many of our vintage parts were manufactured decades ago, they remain unused and high-quality. Some original boxes may show signs of shelf-wear, such as dust, tape, or surface distress from years of storage. Rest assured, the components inside have been inspected to ensure they are complete and ready to help you finish your project without breaking the bank.
