Chip,
Everything you need to know is on their website. I got the shifter from MGW. The only hard part was trying to figure out what was the best order to view the videos because they have them in several different segments. It took me about 3 hours and that included a break to cook, eat and clean up dinner.

It is definitely one of those projects that when you are done, you realize you made it much harder than it had to be and i bet i could do it in under one hour the next time. I watched the videos a couple of times while waiting on the shifter, and then had the video going as i was installing. The kit came with a centering jig and you dont even need to use it. The video explains exactly how to center the lower box onto the torque tube without the jig. I think I can shift faster than the auto now. It is amazing.
