Those converter to flexplate bolts will do that now and then. Mopar still sells the bolt for that, with the special head and as I recall, the special washers. They are not at all expensive and cheap peace of mind. My lesser Mopar, 66 Charger, had ONE of those bolts back out far enough to make contact..you would have swore the bottom end of the engine had come apart! Glad to hear it worked for you Brad!
