These are from the doors, window guides, and collapsible top. The doors are extremely heavy, and are mounted on the inadequate concealed hinges to the front pillar which is weakened very considerably by being almost cut in two to take the hinge. The hinges are not sufficiently well fixed to the door (especially the bottom one). The already weakened front pillar has no rigid connection, owing to the collapsible top, to the rear portion of the body. The Musslewhite type of door fixing is bad for rattles. The cracks in the windscreen we should say are caused by faulty fitting of the windscreen wipers. The two wiper fixing screws have evidently been tightened up too much, this has closed up the two flanges on to the sealed edge of the Triplex glass. We know that local tight fixing on the sealed edge of Triplex will invariably cause a crack to develop. The window guides rattle against the screen pillar due to the general lack of rigidity. (In connection with this front body jellying, harder scuttle isolation rubbers would have reduced the effect considerably). | ||
