There are a number of threads on this search should find it. It also comes with fairly good instructions... I did the entire install from inside the car.
I had it installed within about 45 min. I took my time and even had to answer two phone calls. But I'd say that's about the time it will take. I do most of my own wrenching, but I don't consider myself an expert or anything. I would say that most mechanically inclined people could do this install.
It's been 4 or 5 months and I've had no problems. Also I love the shorter throw, and the look...
