I purchased some inspection hole covers. As they came with only pilot holes for the screws that secure the covers to the wings, I will have to drill the full size holes myself. Could somebody make a recommendation for the size of the holes on the covers and the size of the holes on the retaining clips? I was told that the holes need to be of different diameter. I plan on using P4 screws.

Thanks
