I dont remember if the 560 had a tandem pump with power steering like the 140 body does. You might have to loop it back since the fluid flows all the time. The hydraulic struts also help raise the rear of the car due to the residual pressure in the system, so it will sit lower, different springs or pads. I f the struts dont leak, it is probably bad accumulators, the pump and the control vale are the only moving items
