My 218 is mostly together and this morning I was in the process of mounting the flywheel and torquing the flywheel bolts to 55 ft-lbs per the shop manual when I started to feel the last bolt give out. Sure enough, the bolt thread had stripped out. I guess it was just an old worn out bolt that I should have replaced before installing the crankshaft. Has anyone else had this happen and what would be the best way to fix this problem? I'm sure the original style bolts are unavailable. Would any grade-8 hardware store bolts be OK if I grind off one corner of the head to make them fit? Last but not least, why on earth did Dodge not design the flywheel to be bolted on from the flywheel side??? What a pain.
