64 Tranny Linkage???

I bought a 64 Dart GT vert a while ago and have been trying to put it all back together. The previous owner had done a fair amount of work (including a full engine rebuild), but I am the one trying to finish the work and put everything back togther. I need to figure out what is going on with the tranny "kick-down" assembly. Nothing is hooked up, so I am trying to figure out if I am missing parts, and how to set it up. Obviously the throttle cable/bracket is not original, but it looks like the pivots/linkages are there, the lower arm is intact, and I think I might have the other arms (see pictures). Please take a look and let me know what you think. Any feedback - and better yet, pictures of how it should be set-up, would be GREATLY appreciated! THANK YOU!!!
