Review on High-Quality GM Genuine Parts Front Passenger Side Power Window Regulator - 22895756 by Justin Olson

I had to make both sides of my Corvette 06 with these parts from this manufacturer. They come with everything you need, with all the hardware, but no instructions. YouTube is your friend in the process of replacing them. A screw seems impossible to reach until you realize there is a rubber stopper at the bottom of the door. Pry off this plug and access is then very easy. Do not force anything, this is not work that requires brute force. If your old block isn't moving, then there's a screw somewhere that you haven't noticed and removed yet.
