Yes, I meant item #1. The exact bolt in question is this one:



Passenger side for me, driver's side for you. Not that it really makes any difference !

Not sure that I can drill it and put a bolt through. I suspect that it's a captive thread in the chassis rail and putting a long bolt right through could squash the chassis rail. It'll only be a few turns of the thread that are damaged, if I can clean them out I'm sure it'll be fine.

That's a good link for pics of the underbody tray. I definitely don't have one of those
