A Note on Fitment Accuracy: We manually research and cross-reference our fitment data using vintage manufacturer catalogs.

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.
