I have a cover which came with my West Coast Cobra when I purchased it. It's an indoor cover, breathable with a cotton outer with a soft flannel lining and has reinforced grommet holes for securing it. I've put it on and removed it more than once by myself, and it was pretty easy to do.
I contacted Beverly Hills Motoring Accessories, who made the cover. They tell me the pattern still exists and it is the proper cover for WC Cobras. They've also indicated the fabrics have improved since mine was made, now coming in a variety of colors.

It's probably reasonable that, if they make covers for the longer and wider WCCs, they also make covers for the more popular makes / models / sizes.
Good luck with your purchase.
