    Note on Photos: The images provided are of the actual item you will receive. You will receive both valves as shown in the images. 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 our fitment data using vintage manufacturer catalogs to provide you with the most accurate information possible. However, because we are human and these decades-old resources can occasionally contain errors, we cannot guarantee 100% accuracy. We strongly encourage you to perform your own due diligence and verify this part number for your specific application before purchasing. Please note that this part may also fit other vehicles or years not explicitly listed in our research.

    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.
