OK, just got done. I found somewhere online that the cowl is pressed on with some clips and there were two plastic screws by the weatherstrip.
LaserSVT, you were right, it was a Steeda strut brace. I'm going to leave it off and see how the car drives without it. If I don't notice any difference, I'll just leave it off since it will make life a bit easier when I have to work under the hood again.
Thanks again!
