All early A series engines had these gaskets made in cork for the rear convex shape tappet chest covers and fitted to minis until 1966. At Mini World Australia, we understand the passion for maintaining the authenticity of your Classic Mini and Moke cars. These early cork tappet chest gaskets are specifically designed for the convex side plates of pre-1966 models, ensuring a perfect fit and true-to-original performance. Please note, these gaskets are not compatible with later concave covers, which require rubber types for proper fitting. Trust Mini World Australia to keep your classic beauty running smoothly with genuine parts.
