That's the way the Model T did it, and Louis Chevrolet just copied Henry!
The concept of a torque tube puts the driving thrust near the center of the vehicle, instead of pushing the car/truck along with the rear springs. it's a complicated, and really unnecessary way to get the driving thrust to the frame. However, lots of manufacturers used the process, as late as the mid-60's American Motors cars. Furd quit using the design in 1948, and Chevrolet hung on until the early 50's.
