If you send "Modelman" a PM I believe he has a complete Hydramatic equipped truck. He's a good guy, and I'm pretty sure he would be willing to help out. That throttle pressure linkage is very important to proper shifting and transmission life, and it's got some oddball geometry, so try to duplicate the factory linkage as close as possible. A Dual Range Hydramatic was the first auto trans I worked on, back in 1958!
