I don't know if I can explain mine well. The bung had a rubberish white cover with an aluminum retaining band. I cut the band off, then removed the cover. Then used a vice grip and unscrewed the metal bung plug.
As for cutting 8 holes - what will happen when it rains when you are smoking? If your lid is shapped like mine - all the water that hits the lid will go in the pit.
