I considered doing this when I started building my '67 Shelby clone. I'm not too wild about the looks of the '67-'68 style scoops, either. If I were you I'd measure the distance between the top and bottom body lines where a '66 Shelby scoop would mount and if it's in the ballpark, I'd order a set and try it. No matter which type of scoops you buy, they're not going to bolt right on out of the box, so may as well get the style you like, right?
