Anyone know of a vinyl targa cover?

Had a 914 a few years back and bought this awesome cover that was simply boat cover material sewn perfectly to fit around the 914's boxy cockpit area. It had 4 elastic ropes w/hooks on the ends that hooked in wheel wells.
It was convenient for going to work and slapping it on rather than lugging top out. Kept out rain etc, but more importantly heat. Has anyone seen anything like this? Thought I saw something like it in Tweeks. Anyone have any experience? Thanks, Joe.
