Correct, no holes for the lines. They run right under the rocker panel and over the wheel well. There is actually one bolt hole in the wheel well.

I don't run any air through the trunk. The oil cooler is just under the bumper and the air just flows through.

Supposedly, some people put a GT bumper and valence on cars and just use the holes in the front to let air in. I don't think they would flow enough air to work well.

Nicely done. I suspect those holes do work with the rest of the factory GT kit... But it is hard to argue with your goal of keeping it easy to backstep to original... Beautiful car... Now my desktop
