Sorry, I didn't word that correctly. The original glass hoods and scoops were replicas (size/dimension, etc.) of the original 64/65 metal scoops (like shown in that parts package photo). The altered opening and taller opening scoops you see on a lot of clones and restorations these days are often later aftermarket versions modified for extra height, etc. MANY of the fiberglass companies selling these scoops (as well as 67 Hemi scoops) sell modified versions as compared to the original factory scoops.
