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
This is a high-quality vintage component. As with many New Old Replacement Stock (NORS) parts, the item and its packaging may exhibit minor "shelf wear" consistent with several decades of storage. This can include light surface oxidation on the metal cover, dust, or minor box deterioration, none of which affect the structural integrity or electrical performance of the regulator. These components represent the original manufacturing quality of a bygone era, often far exceeding the standards of modern aftermarket replacements.
