Yea I have 2 springs, the one out side of the tunnel is very hard to see. It hides nicely behind an aluminum tube. The one inside the tunnel is equally as hard to see.

Hayden, I can confirm that the outer spring is connected where you point out in your pictures. The inner spring is as I described. Connected to the short tube welded to the rudder bar and then over to the pilot side of the tunnel.

I have attached some pictures, best I can get right now.
