I used a hole saw after the foam was glassed. It cut the glass and foam like butter. I then touched the inside of the holes with a bit of flox/resin to seal. I guess I could have used the "divots" to attach to the belly but I'm guessing the difference it would make at cruise would be less than the width of the needle on the ASI.
