Here's a link to what I believe is the best EV-100 autopilot mod for the 26M.

BOAT documents his EV-100 below deck tiller pilot mod.
I restored most of the image links.
One of the issues people have is fabricating the ball and socket joint on this AP it's the worst part of the build to make. - and when I added the electronic rudder indicator that eliminated the need to fabricate such a difficult metal part to grind and shape. The fitting that the ball falls into is hard to cut too so let me provide a solution to that.
First off - the whole reason I used the ball was in case the shaft rotated. If you use a pin dropping into a hole it will no longer work if the shaft rotates.
This off the shelf rudder indicator when installed will not allow the shaft to rotate. If you install one of these onto the piston you can skip the whole ball and shaft rigamarole and just have a pin on the end that drops into a hole on the rudder arm - much easier to make.
Should I post a video of the piston ball being lifted out of the cage? Would that make it easier to see?
Anyways, the cockpit till mod that madsrosen did is really a great way to get an AP onto the boat - and an emergency tiller is ALWAYS a great idea for a sailboat that has a wheel.
