I hate to show this photo as it is the error that came from making the holes for the upper cabinet bolts in the original place. It didn\'t work out. Make the holes as far to the outside wall as possible, then when the ceiling is up cut out as needed to find the riv nuts. That way the hole will be inside the cabinet, not outside as in this photo. I had to make a patch to cover this error, or I could have built a new panel. I didn\'t make this error in front!
