I bought my kit from ebay and it wasn't to hard to install. Of coarse I did have the engine out. If you are working on it with the engine still in the vehicle you will need some room to work. You have to remove both shafts and the oil pump which is connected to one of the shafts. Just follow the directions in the kit. Mine vibrates a little more, but it seems to have a little more power, plus I am not worried about those darn things going out. I would replace the oil pump and water pump while your doing it also. You dont want to have to tear back into that stuff after you put it back on.
