At the steering wheel it is only a very small amount to get it to clunk. The tech thought it was in the column but it is not. I took the steering shaft off of the upper shaft and was able to reproduce the sound.
I called their tech support and they told me to get it aligned and drive it then report back. He asked me how I installed the pitman arm as that may have pulled it out of center. I repeated to him: installed box, made sure it was clocked, installed pitman arm, then moved the center link into position to the pitman arm. I didn’t accidentally move the pitman and box out of position. The steering shaft lined up perfectly upon installation as well. The pitman and idler arms were parallel with the frame.
So I’ll give it a shot with the alignment and see what happens.
