Mr Moo (I hope I got that right) on Pelican makes a very nice bag for the top with velcro closures and hand strap. Varioius colors. Fits nicely on the shelf made by the folded rear seat backs. He also makes a cover for the glass area for parking in the sun and is for the Targa. Local guys use them. I wouldn't be without mine. Everything neat and cool.
If Mr Moo doesn't work for you pm me and I'll get you his email address. If interested of course.
