"gear box"?
the TF power steering consists of a pump on the back of the generator, a control valve in place of the drag link, and a'power cylinder' - otherwise the 'gear' is the same as non-power - the car has a totally different suspension/steering, but the pump on the generator's no doubt the same, so no ... can't swap car power steering into a truck
