We utilize high-resolution photos of our current physical inventory rather than generic stock images so you can verify the specific condition, markings, and authenticity of this vintage part prior to purchase.
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.

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
As with all vintage New Old Stock (NOS) parts, this item may show "shelf wear" such as light surface oxidation, dust, or minor finish imperfections from decades of storage in original packaging. These characteristics are typical of authentic vintage components and do not affect the functionality of the part. Our pricing reflects the rarity and historical value of these original American-made treasures.
