I'm not 100% sure of the correct name of those insert-nuts, but I call them "riv-nuts
" or "nut-serts". They are commonly used to hold mirrors on the side of a door, luggage-racks on a trunk lid, etc.
I gotta say that I have never seen them used on a cross-member. That is usually nut-and-bolt or rivet territory.
Yea, I am lucky that I had the welder. I think I would've been screwed otherwise.
