It can be done. I assumed there was a cable running through the glass so I never took mine off. I was just going to get a replacement window rather than filling in the hole with RTV and a plug but I was out in the garage yesterday and decided to give it a go. To my suprise, no hole. The antenna was inductive. Bonus.
No more OnStar antenna.
Much more
