Rear suspension question......with pic

[vmax84]

Going thru the rear suspension on my 1980 Invader 340.   So far, things look pretty good.   All the shafts came out easily, but am puzzled how this shaft comes out.   It's the shaft where the shock hooks onto.   How do I get it out?   Do I need to split the rails?

The rails need to be split, or remove all the stuff behind it and slide it out the back.
