I think it has been off the hood before and the person who reintalled the unit could not find the correct rivets. So, he took some of the bolts from the sides of the boxes and threaded them into the hood frame. Hence the missing bolt on the sides.
Here is another shot of a 70 hood that took the bolts with the u-nut. Convinced the 69 ramcharger was attached with rivets and the 70 ramcharger with bolt and u-nuts

I have had multiple 69 ramcharger/air grabber hoods over the years, all of the ductwork is riveted to the hood, the only bolts are on the outer ends near the fenders.
