Kickdown linkage rod length (A904)

I have a 1970 Dart SL6/auto, and the other day I was surprised to find that my kickdown linkage isn't connected to the throttle at all! From diagrams I can tell there is supposed to be a rod between the kickdown linkage and throttle arm. I can make one pretty easily, but I'm not sure what length it's supposed to be.

Can anyone measure the length of this rod (hole to hole) on their car and let me know? I suspect the length might be the distance between both linkages at rest, but the kickdown linkage seems to be spring loaded so I can't say for sure. Luckily I haven't driven around too much like this.
