Well guys, you'll probably want to hit me upside the head, but I figured it out......just take the coupler off, and put it on out from under the car 
There would have been no way to slide that input shaft on from underneath. I had to tap it on with a hammer, then tighten the pinch bolt. Once I got it on, I ran into another problem. The bolt holes holding it to the frame weren't lining up. The gearbox was hitting the header. I noticed the old one had some metal grinded away, so I had to do the same to the new one. I just got done flushing the system. I'm about to reconnect the hoses and see how she runs (knock on wood!).
