So, this should be easier than it is. I removed the headlight lens unit from the car, took less than two minutes. However now I can't get the lens off. Different posts have said to take a utility knife and run it around the gap between the body and the lens. I've done that but still no luck. There are two screws that I'm puzzled by. One is inside the unit where there isn't any access to, and the other is a 6-8mm torx head on the back that MIGHT screw into the lens as additional fastenin. Any ideas? I want to get the lens off to repolish it. It's badly faded.

Thanks!
