Thank you, Jason! From what you are describing, sounds like the below that I have is correct. Would love a photo if you are able to grab one, as I am curious how far that spring really stretches... I wrote the below before seeing your post.
Here is the picture where it is attached to the airframe. This is where the old, broken one was attached. The second picture is the back view of the 'post' or 'tab' that sticks up from the rudder bar and attaches to the rudder cable. The third picture is the front view. This is the only place I see that would make sense for the spring to attach to, but it just seems like that is too far for it to stretch when the pedals are neutral....
