| HS.{Lord Ernest Hives - Chair} FROM DA.{Bernard Day - Chassis Design} ORIGINAL DA{Bernard Day - Chassis Design}1/M21.6.28. X 7480 X 7500 X9613 SUPPORT OF STEERING COLUMN WITH CAST DASH. We thank you for your HS{Lord Ernest Hives - Chair}/RM{William Robotham - Chief Engineer}5/LG18628. It would appear from this that the use of 2 bolts only at the top for the scuttle semi-isolation would be satisfactory, the steering column being sufficiently steadied by the cast dash.
