Detailed Vehicle Fitment:
This original Ford part is designed exclusively for the 1937, 1938, and 1939 Ford Flathead V8-60 (60 HP) small-block engine family. It will not fit the later 1940 V8-60 blocks or the larger 85 HP / 95 HP / 100 HP (221/239 cubic-inch) flatheads. Standard size rear mains are incredibly difficult to find in NOS condition—ideal for a high-end period-correct automobile restoration, vintage midget racer, or traditional hot rod project.

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 our fitment data using vintage manufacturer catalogs to provide you with the most accurate information possible.
