I scored a pair of very nice used, but original GT/CS scoops for $150 bucks. Never know when someone will run into you, so they are in my save pile.
These look to be the real deal and must have came from across the parts counter early on. I would submit that the grills did not come with them. A second part to order if you needed them. With that the sellar may not have them. And the holes to install them are drilled later.
