Progress on my 340 Hood Scoops!
I made a template from the scoop. I placed a long sheet and punched the studs thru the the sheet.
I drilled from the bottom side of the side where the "red outlines" are located.
I place the template on top of the hood and placed nails in the 4 holes from where I drilled the "red outlines" to find my placement. Then I drilled the remaining 4 holes from the topside.
