Bolt on 6 pac scoop for 74 duster?

Anyone know where to buy a good fitting 6 pac scoop to fit on the hood of my 74 plymouth duster? Im looking for one that bolts on from the inside of the scoop so no mounting screws are showing. I found a decent looking one on the website below but it might be a hair to wide for the front. Any suggestions? All help appreciated.
