Will GM 200r4 work with factory floor shift location?

Let me make sure I understand you correctly. You want to keep your shifter and the rod that goes to the upper bell crank and the upper pivot point? If this is correct then you would still need a lower pivot point for the upper bell crank to function. I guess it would just as easy to hook a cable up to the bottom of the shifter right where the upper rod attaches. I've thought about this idea a lot in case I can't use the torque shaft. Just remember that the direction you approach the shifter from determines whether you're pulling or pushing the trans shift arm.
Does this answer your question?
