MTD Snowblower Muffler Bolt Bracket: Redux

Nearly eight years ago I replaced the OEM bracket locking the two long bolts on the MTD snowblower’s muffler to prevent them from loosening from vibration:

Well, it happened again, with the top bolt working its way out, so those little crimps weren’t enough. As before, I watched it happen and saw the bolt fall sizzling into the snow.

Verily it is written: When brute force isn’t working, you’re not using enough of it:

I renewed the Never-Seez on both bolts and, for good measure, dabbed some on the third bolt securing the muffler bracket atop the engine block.

That machine really vibrates!
