Your half moon would be 20" wide x 10" tall. I would increase this to 21" wide x 10.5" tall to add a 1.5" to 2" grease bridge. Make your opening at the top of your firebox this will allow for either the tuning plates or reverse plate to be a continuation of the opening. I hope this helps and if you have anymore questions feel free to ask. :D
