Throttle Cable Components/Linkage

Attached are several photos of my existing throttle cable linkage. Is this common, or are yours somewhat or radically different from mine? I have a non-original 340 ci in my Dart, which may explain why the linkage is the way it is.
I purchased (photo attached) what was advertised/ described as a replacement spring and bracket setup, but it is significantly different from what I have now.
Let me know what your linkage setups look like if you can, please.
