Good morning Spud........
www.letastopshop.com might be able to help you.
An ex maxum dealers if they have one lying around or get a hold of your local canvas shop see if they can make you a new one.
And to answer your question...I am pretty sure that would be a custom job done by a canvas shop.
Some people get a full length cloth that snaps over the clear in the front to block the sunlight. FYI
Good Luck
Roger
