Seems my post (post 8) about the soft engine mounts hasn't been understood.
Let's say the driver is turning left. The front of the engine/drive line is held fairy well in place in the chassis by the front engine mount. With the soft engine mounts, the weight of the engine and gearbox want it to keep going in the same direction but as the car goes left, it moves the right side of the car a little. That takes the back of the A frame with it because it is attached to the flywheel housing. That turns the axle to the left. Now you have the steering AND the axle steering left. The front and of the torque tube has also moved to the right. That turns the rear axle to the right, exaggerating the "axle steer"(for want of a better term).
In other words, the engine and gearbox unit is rigid and so is the torque tube and back axle. They articulate at the universal clam shell and add to the steering initiated by the driver. Result....Over steer.
Henry had it right and once again, our "improvements" detract from his design.
