🚗 Applications

Primary Fitment

1960–1967 Chevrolet Corvair

  • All engines

  • All body styles

  • All trim levels

  • Correct for factory AC‑supplied oil filler cap

Secondary / Cross‑Catalog Fitment

AC FC‑series caps were used across various GM divisions for small oil‑fill tubes. FC‑31 specifically appears in:

  • Chevrolet compact platforms (Corvair)

  • Some early GM industrial/utility engines using AC‑spec filler tubes

This cap is Corvair‑correct, but can physically fit any GM oil fill tube with the same twist‑lock diameter.
