By the time that guy vibrates apart, I will long be dead and buried.

I assume this is just precautionary or have you noticed a problem?
No problems, just tweaking. But if you want to know whether your frame is properly grounded, turn on your lights and fans and put an inductive ammeter around the little black wire that runs from the passenger side cylinder head to the firewall. If it's carrying more than 15 amps, do some additional grounding.
