After lots of research I found the information I was looking for on Jeff Shultz's Sonex Building Web Site. The reducer bushing was not shown on the plans and I was not sure if the wrong bolt size was specified or if I had the wrong size rod end. Lucky for me, I had ordered some earlier that were 3/4 inch long that would work great if they were cut down to size. After getting the bushing down to size is was just a matter of using a bolt and other bushing to hammer them into place. Now with that done, everything else went together as to the plans.
