I did mine a while back and I am a DIY'er. Do one mount at a time! Lift the engine with a piece of wood across the oil pain, remove the fan shroud to give you more room to work. The driver's side is the most difficult but, it is "doable". Just take your time, and enjoy all the money you will be saving and the satisfaction of doing it yourself (priceless in my book).
