In the UAII instructions you have 4 thin pieces that surround the inside of the monitor area whick the plext/bezel mount to. In instructions the screw through the plext, which I am not to excited about as I have done that in the past, and I know there is about 50/50 chance that I will crack or break it in the drilling process. I was looking at some of the photos on ther site of other UAII that have been built and dont really see the screws there so I am guessing there may be another way. Does any one have any suggestions.
