Note on Stock Photos: Due to our inventory of multiple identical units for this specific part number, we utilize representative stock photos for this listing. You will receive a component that strictly meets all listed specifications and fitment requirements. Please be aware that because these are vintage parts, minor cosmetic variations—such as surface finish, color, or production markings—may exist between different manufacturing runs. These slight aesthetic differences are a result of historical production processes and do not impact the part's integrity, performance, or authenticity.
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
Our vintage parts have been preserved in climate-controlled storage for decades. While the components themselves are brand new and have never been installed, please expect typical "shelf wear" such as dusty original packaging, minor surface oxidation, or light finish scratches. These cosmetic imperfections do not affect the mechanical integrity of the part. We offer these rare finds at unbeatable prices, allowing you to complete your project with high-quality, period-correct components without the modern premium.
