Replacing Front Grille Side Brackets

[D-n-Tyke]

Swapping out the front grille on our 1969 C20 Suburban with a better used one. When I picked it up I didn't notice that the PO removed the side bracket to use on his new grille. Not that big of an issue, my original grille has the brackets. I just am trying to figure out the best/correct way to swap the brackets over. I know I can just use standard aluminum pop rivets, but I like the look of the original style rivets better. Is there an easy way to reinstall the brackets using the original style rivets?
