In a Hotchkiss design ,the leaf springs take the engine torque,no torque tube.
Racecarl, all rear axles are exactly the same amount of work to install.What bolt pattern will you have on the front wheels? Be nice if the rear matched the front.less money and time wasted redrilling axles.The usual welding involves the spring perches and shock mounts.I have actually done the swap twice,using Chevy axles.A very easy job for a hack like me.
