Here's another shot of the final fastener pattern as indicated by the temporarily placed raw rivets. To transfer this pattern to the hoodscoop, remove the rivet guides, precisely align the scoop with the pre-drawn painted outline, and tape it securely in place. Mark the scoop for drilling by poking the grout marker through the holes in the hood from below. This will transfer the fastener pattern to the bottom side of the hoodscoop flange. Now drill 316-inch holes through the white dots on the scoop flange with the Unibit.
