In Need of Super 6 Kickdown linkage

I'm inheriting a two barrel intake/exhaust manifold as well as a carb from my brother who was running this setup in his 4speed. I want to install on my slant 6 '70 Dart Custom but need the kickdown for the 904 trans can anybody out there help me find one??? or at least a good diagram so I can fabricate one myself??Thanks -Mike =P~
