if you have a 4 headlamp charger or turismo kickin around - take the 5-0 scoop over to it and put it on the hood - backwards
now if you cut a ^ shape in the middle of what used to be the back wall of the scoop and give it a gentle pull on your knee to bend the corners towards you - it will fit the hood - and mirror the indented hood lines better than ya might think before you see it
then to keep the shape - a short piece of I beam curtin rod - long as the scoop is wide - with a hole for one front corner stud drilled in , adjust bend in scoop as needed - mark curtin rod to drill at right length - bolt up , fiberglass notch and remove curtin rod
finish as needed
I had one on my turboed turismo - if I coulda scooped a through hood intercooler I would have made it a shaker style deal by just cutting the rectagular hole in the top
I contacted the person on the Shelby forum that supposedly has it, and the kit is for sale, but he thinks the scoop is aftermarket, which it could be, but I have not been able to get him to send photos after requests. I wish someone would take a few closeups with measurements and post photos.
