Excellent guide. You have to have a nice sharp spudger to get in to start prying the baseplate. Once it starts, be patient and don't rip; just gradually pull. The screw that does the adjustment isn't a screw; it's a slug so the movement is limited a couple of millimeters and then it falls out. I also found I had to bend the metal plate (to which the screw is attached) to give it a little extra springiness. It appears that between the adjustment and the bending, my trackpad has been restored! Thanks EVER so much.
