Confirming our conversation on this subject, at the moment we feel that the lamps go more than they need owing to the torsional flexibility of the side channel where they are bolted to the frame. We do not think it will require more than a light member between the supports of the lamp to stop the frame twisting. We recommend as a simple experiment using the split tubular type of cross member, i.e. as used for the front engine mounting, and if necessary bending it to avoid the vee of the radiator shutters. We want to avoid drilling the frame if we can in this experiment, until we have at least decided whether we are attacking the right point. The complete frame stiffening which includes boxing the side channel from the dashboard forwards is of course a separate issue, and we shall be able to see this mocked up on the bump chassis before we think of fitting it to one of our cars.
