ummm yeah you really over-worked yourself! lol
no need to pull the wiper blades off. just get them in an upward position, turn the car off.
and then there's the argument that your cowl piece is ONE piece. sure. but it's got enough flex in it that you can install it by just lifting it up. so you really just did more work than you had to. and im not sure what you had to remove to get the cowl piece to sit in there aside from pos stock rubber and the plastic that you break off of the cowl.
but good job
