You just reuse the screws you remove from the block off plate, identical mounting locations for the duct. When you put the duct together make sure the labels are on the outside of the duct. If they are on the inside you assembled the duct wrong. You shouldn't be able to see the labels looking through the intake/duct from the front of the car.I do have a question to other tech owners that adapted is there a ford part number for the bolt when installing scoop/duct for cooler or is the same bolt for block off plate ?
