Years ago I was building a play structure. Part of it was a mini rock climbing wall. The construction manual was very specific and went into great detail about which plastic rock went with which pair of holes on the wall. However, none of the rocks were labeled, and it wasn't at all obvious how they matched up with the diagrams in the manual. Each rock had a pair of screw holes, and the wall also had pre-drilled holes, but the spacings didn't seem to match up no matter how I arranged them. I called customer service, and they didn't know how to match them up either. They gave me contact information for one of their installers. When I called the installer and explained the problem he just laughed and said something to the effect of "Yeah, the holes don't line up. Just put the rocks wherever and drill new holes."
