One last thought, there are two versions of that bracket that mount on the side of the transmission (the one with the little o-ring hole). I discovered this when I was doing my conversion. I am not sure which one is the correct one for your car, but you will know if it is right once you drop that linkage down through the hole in the hump. And for reference, a 2 3/4" hole saw bit is the perfect size for drilling the hole in the side of the hump. Just something to think about as you are putting it together.
