How do you fasten the grilles to the plastic inserts on these hood scoops? In other words - how do you use the pins on these grilles to secure them to the inserts? As for the scoops themselves - were they just attached to the hood tabs with sheet metal/self tapping screws from the bottom? Thanks for helping a noob. I've never actually seen this hood fully assembled!
I asked that exact same question a couple years ago. This should be what you are looking for http://www.v8buick.com/index.php?threads/what-keeps-the-hood-vents-in-on-a-1970-gs-hood.308869/
