In your video it was above 🙂
Thanks for all your help!
Actually I figured out a workaround. The problem was with shrink wrap on the bottom of the stack, the holes looked perfect, but the cockpit rim got distorted. By creating TWO Shrink-wrap modifiers (one above and one below) and assigning them to appropriate vertex groups allows me to get the best of both worlds- something I can see coming in handy later when I’m dealing with much more complex surfaces!
