| -3- Modern American practice does not rely on the frame alone for this result. Take for instance the 1935 Ford Sedan: Between Wheels D to R F to D Bare Frame: 475 565 2970 Note: Fr Wheels to Dash is only 19½". Frame is not complete till body shell is mounted, since body floor is used as top-plate of X - member. With bare body shell: 2100 3305 5705 With toe board and and metal cover over transmission: 2365 3905 6175 With engine: 2440 3650 7360 With front fenders radiator shell and core; and running boards: 3225, 4360 12400 Note: All sheet metal including radiator is mounted solid and bolted into frame to reinforce stiffness. Complete car with rear-fenders, in- strument panel and steering gear: 3420 4700 12500 Here again are some interesting figures:- Wheel Cens D to R F to D 1934 Olds 8 Sedan: 2030 3440 4960 A similar car on which the frame had been cut away, and the body (which had already run 17,000 miles) was married up to the front and rear axles by special devices, gave:- 3640 4200 25600 The front end of this car was entirely free from shake. The rear end was not stiff enough to give complete freedom from rear-end shake. We now have a huge library of these tests taken both at Cadillac and at the Proving Ground, by the same method, and feel that the necessi- | ||
