Actually wondering the same thing myself. I would like to use the original Tron straight shaft along with the modern under pinnings of the Happ 8-way heavy duty stick. Basically, have it look factory from outside the cab. And to take it a step further would like to incorporate the ServoStik too that way I could play 4-way and 8-way games properly. I know the ServoStik can be done, I read the thread on that, but haven't found anyone combine the Tron and Happ sticks yet, at least the way we envision it.
