I think you can find a new cover if you're patient. Many owners are putting in Fantastic Fans. I'd recommend a fantastic fan to you--they create a very strong draft, something none of the old vents did. You'll be glad you did. It's really not that hard, except you need some kind of contraption to get you up on top without oil canning and creasing the shell.
