I've got it...

You can make a bracket that mounts to the back side of the throttle lever at the transmission kick down stud. Similar to the small bracket (flat piece) in this picture. The large hole is for the kick down stud and the small hole would be for the spring. I'm sure you could use all kinds of things to accomplish the same task. It just needs to be strong enough not to bend or tare out from spring tension.
