Taillight feedback wanted

[G/A-body]

I ordered some 69 Camaro Billet Taillights from Marquez with the intention of using them on my 79 El Camino. Just laying them on the bumper my first impression is that the proportions are off. Maybe because the flanges show and I am used to the size of the originals. The bumper will be narrowed about three inches in the middle. Take a look at the pictures and offer me some feedback. I set them out on a couple different configurations.

Thanks in advance
