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.
Note on Manufacturing Provenance: We maintain an extensive inventory of vintage, Made in the USA oil seals from premium historical manufacturers on our shelves. To ensure data consistency across our catalog, we convert all specialized seal brand numbers to the standardized Victor numbering system. Due to fluctuating inventory levels at the time of purchase, you may not specifically receive a Victor-branded unit; however, we guarantee you will receive an American-made seal that 100% interchanges with the Victor part number listed.
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.
