Need six pack scoop

I need to know where some of you may have gotten a six pack scoop that will fit on a '74 Duster hood. I'm guessing all the Duster hoods (at least '73-'76) have that raised center section which leaves only about 24" between the edges. The MAS scoop like one of our members here is selling is too wide to fit on top of the flat section. Anybody have one that fits your Duster (got pics)?
