Have you checked with the dealer? Price was not too bad for the single mass (the one you want) flywheel, around $300 or so. Personally I welded up a m102 16v flywheel to fit my 3.0 but I really do not recommend doing it unless you know a welder with extreme precision and knows how to do decent silicon bronze welding on iron. Not something to trust the local muffler shop to. Although I did save 15 lbs on the flywheel by doing it which was quite nice.
