Hey all,
Got my DMD installed, stealership charged $100 to do it including new seal and serpentine belt. I probably could have done it myself, but I don't have time to have a my car apart for a day or two if something went wrong. For $200 total and no trouble for me, I'd say its a mod well worth doing. If you're thinking about it, do it, it makes a difference. Car feels much smoother, although I don't know if it will hepl engine life much, since I'm revving higher and more often that I used to
