Model A Timing Advance System
You'll never have to touch your spark rod once you have installed this kit! Installs inside the valve chamber and replaces your lower distributor shaft. Gives you a full 30 degree range and requires no modifications to distributor, engine or timing procedures. You have to remove the valve cover to install, so don't forget the manifold, valve cover, and oil return pipe gaskets when ordering. Genuine Nu-Rex brand. U.S.A.
