I would just take the gearbox out. It’s not too difficult a job then you’ll be able to see what’s going on.
I must admit when you posted that picture of the damaged bell housing cover I couldn’t see how the flywheel could have done that....and now you know. The bolt coming out could be the cause OR the symptom of your vibration. I’ve heard that a worn pilot bushing can allow the clutch to go slightly off centre and cause major vibrations.
This reminds me of when I took the cover off my old differential and the remains of FIVE ring gear bolts dropped out. There had been some alarming noises going on!
