Does anybody know where to get 2 balancer shaft bolts (the nearly 7" bolts) ? I have tried 2 different dealers and they tell me they are discontinued.I can't find a bad engine at my local scrap yard.It is for an early 2006 2.5. Nissan part number 12293EA000. Online a couple of dealers do show the part,but then comes back discontinued.I don't care if they are used.Please help!!!!
