If it is on the front D. side of the engine like mine it can all be done with the engine in. I'll assume a SD has just as much if not more room than my F150, Rockauto should have everything you need. It will be far easier with the inner fender flap removed. Hardest time I had was with the top and bottom bolts, very little room to get to them but it can be done and with a very small movement of the wrench.
