| -2- Body Mounting. The Big Packard has 16 points of pulling the body on to the frame. The 120 - 28 points. They say the body definitely affects the overall stiffness. They get 2500 foot lbs. per degree from the frame alone, they say. They think we shall find we are too weak. ---------- Noise insulation of bodies is being extensively carried out. We have samples of the combined deadening and absorbing materials used. Roofs and floors are especially treated. Dashboards have as many as three layers of the deadener they showed us. They also spray a rubber compound for large flat surfaces, especially the floor of the Lincoln Zephyr. Da.{Bernard Day - Chassis Design} | ||
