Ken,
I found the backing plates were set up for the nosewheel Sonex. Heresy! Somewhere a witch needs to burn or something. So check that, you may need to make a set with alignment for the taildragger.
Also make sure you press in the bearing races with a hydraulic press. If you don't, your aerobrakes will slowly do it for you, meaning you will have to keep tightening the castle nut, adding washers, and generally cursing your lot in life.
I originally used 3/16" hardware but the assembly wore and the wheelpant would rotate back and forth. To make the 1/4" bolt work you will need one of those small all-metal clench nuts - NUT, STOP MS21042-4.
Looks great!

The pictures were lost somewhere.

In the 3 point attitude the plate was 8 degrees nose down and the airplane was 9.5 degrees nose up. So, our hole pattern needed to rotate 17.5 degrees. We used this simple setup.

We used a piece of flashing to make a template. The blue lines show the nosewheel configuration, and the red lines are our new tailwheel configuration.
