Those are not "early" scoops. I had a set just like your photos show. Bought them at the dealer in 1972. $28.__ each. Nice price right? I came to my senses and repaired the scoop I bounced off of the garage door opening, so, I have originals on my car. And, sold the dealer bought scoops at a swap meet long ago. "Trembczynski" was dry markered on the boxes.
The scoops shown are good for a later built car. Yet before the dropping of the ductwork to cool the brakes.
Seems the maker of the early type scoops had to machine the back (mounting surface) of the scoop and had a funnel-like vortex mounted to it. So when you looked inside it was a clearly two piece base. Then the scoop part you see on the quarter was glassed to the back.
I think J.D> might have photos that show this. And I think his photos might be of my car's lower scoop internals. I posted them on the Pre-crash forum.
To summarize: Yours look good and would be correct for a not early built car.
