| -3- A further reinforcement of the body structure can be achieved if the front door is made to act as a tie between the scuttle and the main rearmost portion of the body. This calls for some form of lock other than the orthodox bolt lock and it may take the form of a Silent Travel type lock at the waist rail. In connection with the de Ville Extension, it has been found expedient to cause the demountable cantrails, whether folding or sliding to act as a tie between the screen pillar and the centre pillar, by the use of a rigid attachment at both of their ends. Experiments have proved that increased rigidity is obtained in the case of the Sedanca type of body by attaching the scuttle face rigidly to the dash board and the chassis frame, with no attendant disadvantages. This is done by replacing all the rubber washers of the top scuttle isolation bolts by similar washers of aluminium, using the bolts and nuts, etc. supplied with the chassis. The large hole in the dash is bushed with an aluminium washer. See Section 'l', Sheet 6. Similarly the side scuttle buffer rubbers are replaced by aluminium blocks. See Section 'm', Sheet 6. | ||
