S.S. SIDE STEERING TUBE SPRINGS. x7450 x7430 With reference to BY4/G14.5.29. We are not yet in a position to recommend any departure from the present 1500 lbs/in. side steering tube springs. In any case if we do change it will not be to anything stronger than 2000 lbs/in. You will have noticed from Hancocks reports that we have still some work to do on the S.S. steering.
