Interesting. Almost the same front end as on that coupe. Somehow this does not look goofy. I think it's that the headlights on this one don't seem all bug-eyed. Recessed a bit more. It just doesn't work on the flatter front end of the '65/'66.
In the 2000 version of the movie Gone in 60 Seconds with Nicolas Cage, the "star car" was a 1967 Shelby GT500 Mustang that was codenamed "Eleanor." For this movie, the car had a very distinctive look with a body kit and color combination. It was so popular that a company started producing official GT500E cars. The E stands for Eleanor. @planetdrumz picture appears to be one of these official replicas, it's just a different color scheme than the movie car.
Naturally, when something is popular, people try to copy it. There has actually been some extensive legal drama around this up to and including confiscation of unofficial cars. Those copies also appear to include making a non-1967, non-Shelby Mustang look like Eleanor like your first picture. And you're spot on that it looks weird because the kit wasn't originally designed to work on the flatter front-end of the 65 notchback.
Look into the legal stuff if you're in the mood for some interesting and potentially frustrating reading.
