Hydraulic ram for autopilot for 45 CC

Hi there. Bought a '93 45CC recently that was a little bare systemswise and one many things it needs is an autopilot. Id like to go with a hydraulic ram but there seems to be no way to attach it to the rudder post. (Well, there is always a way but its going to be a lot of machining and engineering). Can anyone advise as to how they did it?
