I am not sure about the 35 Mk III, but I have installed a below deck autopilot on my 35 Mk II, and can't stress enough how important it is to have a very beefy attachment point for the fixed end of the hydraulic ram. I believe the forces are in the neighborhood of 1000 pounds. Mine is attached to one of the two longitudinal stringer that are located on either side of the cockpit floor. I fabricated a beefy stainless steel bracket for the attachment. The location and alignment for the attachment is critical and difficult because the rudder shaft is not vertical and the ram would not fit transverse in the under deck space. This require all sorts of compound angles. I can provide detailed photos for the 35 Mk II if you are interested.
