FWIW, I think the cover for my Pantera was a Cover King - fit very nicely! I just tossed it a few months ago as it was old and tearing. Let us know how yours fits once it arrives, as I need to get a new one.
As a point of reference, I ordered an "American Armor RipStop Car Cover" from Empire Covers (their most expensive cover!) for my 69 Cutlass convertible, and the fit was TERRIBLE! I had to return it because it was so bad.
