machanical linkage ?

Hello fellow gear jammers. I have a question about building a mechanical linkage for my drag truck. I realize for my Dart the best way to go is to use a hydrolic setup. In an effort to make my launch more consistent, a mechanical setup is the way to go. The problem is, my Dakota came from the factory with a hydrolic style (slave cylinder) setup...... I'm building my truck for a stick shift class, and the majority of the participants have all advised to go with a manual setup. From what I know, I'll need a Z-bar of some sorts, and a pivot point. Does anyone have any more information they could point me too. I will be using my 63 Dart's setup as an example. I plan on building something using Heim joints and tubing for strength. Thanks for any assistance in advance.
