D4 7U Steering Clutch issue

D4 7U Steering Clutch issue was created by SkyMoCo
I just acquired a D4 7U that was parked in a machine shed in the 80's when the right steering clutch would not work. After cleaning the old gas that turned to jelly in the past 35 years, it fired right up. All the gauges work even.
The right hand steering level pulls all the way back with some effort, but not much. I took this picture, (sorry about the quality, the video I took did not turn out). When I move the levers the joints with the red arrow move just fine. When I move the left level the trunnion that the green arrow points to moves. But when I move the right lever the trunnion that the purple arrow point to do not move at all.
I am thinking the pin that moves the trunnion may be broken and this means pulling the cab and transmission cover.... See attached photos...
