I don't ever think about a car with out a clutch. But Miler Mike explaned to me that his car, the Creel lakester, didn't need a flywheel blow shield because it has an automatic. And it has also been explained to me that cars with motorcycle engines are allowed to disregard rules concerning the plane of the flywheel. This is because no motorcycle engined car has blown a flywheel at Bonneville in the memory of anyone. Nor has any Packard powered car blown a flywheel at Bonneville in the memory of anyone I have asked. But I still need a scattershield. Dosn't seem fair.
