For years the only available throttle linkage ball joints for the Healey 100 were visually incorrect and made from steel.
A.H. Spares have managed to discover the OE manufacturer. They have been made using O.E. tooling in brass, with the only difference being that they now have multiple adjustments for a precise setting.
You can now buy these accurate reproductions from A.H. Spares “The Original Healey Parts Specialists.”
