Check out Autobarn.com. I just got my all-weather custom cover through them, and it fits like a glove. It's got grommets for tie-downs, but it fits so perfectly you practically don't need them! I had a cover by the same guys on my 73 Charger, and it was a pretty good fit, and very durable. This is the same material, but I am blown away by the way it fits.

No affiliation/relation/sponsorship blahblahblah, just wanted to support a good product.
