Wayne,
I actually have that scoop here , ( no ideas what its out of ) and its REALLY far off. Might be easier to make one from scratch. And If I do that, I''l just use the resin sixpack hood I have on hand already .
Best I can find out so far with my digging is the sixpack hood car is / was a 1970. The wedge looking scoop is the 71-72 car
