Rotate the front set of drivers so that the main rods match the positon of the main rods on the rear set where the linkage is hanging down.
Use the front set of drivers as a reference as to linkage position.
If the bolt holding the linkage to that rear wheel on the rear set of drivers is loose ( do not remove it).
Its a matter of pulling the "out of place linkage" outward a bit, this will allow for free rotation of this linkage to reposition it. There are notches when you push it back in to hold it in place. Snug the bolt back up to hold it there.
As Dave mentioned you should have a tool in the box for tightening the bolt
