The photo below will show you the correct assembly order and up/down orientation for the linkage parts (sorry, but I don't have the name of the original poster so can't provide credit).  To assemble, just start stacking the parts on the crank arm spindle, working from right to left.

FWIW, I did a lot of experimenting with this assembly last year to see if I could discover the purpose of the spring and the eccentric bushing.  My conclusion is that the eccentric bush is there provide some compliance in the linkage (so that the long connector arms don't bow or get over-pulled), while the spring is supposed function an anti-slop device (which it might if the tang wasn't broken off -- which it almost always is).  I concluded that the spring has nothing to do with the 'auto-rise' function (which was just Nissan's way of saying the the wiper motor parks the blades a bit higher than their lowest wiping-mode sweep point).

Very good photo.

Posting in response to your conclusion.  I do not believe what you wrote is correct.  Pretty sure that the third part on the right is a cam activated by the spring.  The parts in the photo when all correct and functioning are the basis of the park along with a motor that reverses.
