Tiller Arm for Raymarine Type 3 Actuator

[kaakre]

I am installing a EV400 Sail autopilot with a Type 3 M81202 hydraulic ram. It appears that Edson tiller arms will not work due the M81202 rod end being 1 inch thick and the slot in the Edson tiller arm being only 3/4 inch. Am also looking at Jefa arms but they result in aluminum being mounted on my stainless rudder post.

Has anyone out there installed a Raymarine Type 3 with a new tiller arm? If so, where did you get the tiller arm?

In the alternative, I could go with a lead on a good machinist.
