Here you can see the simple mount. And gusset. I am using 1/4" steel. I had to cut the spindle top to be able to mount the spindle as high as I need it and clear the bolt. I could have made my arms another 3/4 longer and move the whole thing further back on the plate. The spindle would clear the bolt. BUT, I decided the arm being short is important. I did have to make sure radius was enough not to mess up the steering geomtery. Also, I decided a gusset on one side was more than enough.
