How can I fix door lock movano year 2000?

The linkage rods seen with the outside door handle off have come off the lock mechanism and I'm not talking about the lock barrel as every video and blog seems to talk about. I can get the lock down and think I have put the short rod with the screw thread in the right place it's the long rod that I can't get to stay in where I think it goes it keeps falling off pin when I refit back into position. Has anyone got a picture of this assembly? Or can set me on the right path?
