What you need
On the 81 hunter, the ports are Gray marine, they are sold through balmar, JSI, (Johnson sails inc,) of st. pete florida, sells the entire port or any desired detail of the assy, I just bought two port lights( the clear plastic lens) from them for about $45. ea. I asked them to order the lens without hinge holes, so i can align the new holes with my existing holes, the size you're looking for is 7"H x 15" L,
