I've got new and used top covers available. These are made from Sunbrella, which is a much more durable and watertight material then the Top Gun and Moisture Guard fabric that most covers are made from.
New is $120 + shipping for the basic top cover, I'm happy to do custom add-ons
The used one I have is about 2 years old, I''ll sell it for $80+shipping
If your mail account accepts attachments, I'll send some photos later if you are interested.
