Quoted from firefighter:You are over thinking this as all you need to do is get the hardtop set where it best fits the inserts and then tape it down. Take a sharpie and mark the side of hole where it needs to be ground out. Remove the hardtop and take a drill and small bit and egg shape the hole so you can get access to the hole. Set the hardtop back on and double check to make sure all holes are accessible Make sure all plastic dust is gone before you stick the hardtop down.
Ah, OK. This is what I was thinking. Modify the hard top holes to allow access to the homes already in the Playfield. Thanks for the clarification!
