Being an ex-transmission guy, I've seen a lot. Once, I saw a C5 that sheared the flywheel bolts and the flywheel went through the floorboard and dashboard like a buzz-saw. The owner is lucky that he got his feet out of the way fast enough.

You're lucky that the bolts didn't come loose. Brandon is lucky that his didn't come all the way out. LocTite is cheap insurance, use it.
