Assuming my memory is correct now that I have had time to revisit this, there are only five retaining clips which mount the pad from the passenger side to the center of the pad. Then there are only two screws above the cluster and nothing securing the far left driver side of the pad. This is the original GM design and this is the way NPD and other aftermarket pads have been built in order to replicate the original factory design (I assume). I made two modifications. I added an additional screw on the far left as shown in the photos below and the spacer as mentioned in the previous photos.
