@Stephen A Titus asked for sources for a tonneau cover. I only know the pricey generic answer, but speaking of tonneau covers I picked up my new bespoke one today. I had an upholstery shop make it up.
See https://www.flickr.com/gp/farsightful/9Zwq7o for the new one in the foreground and the one I've been using in the background. Especially if you zoom in you'll be able to see the key feature I ordered: a longer central zipper. That and a slanted zipper on each side allow the new cover to be zipped back to about the size of a quarter tonneau. I need this because I slide my seat back too far for the short central zipper. With the stock zipper dimension I can't drive the car with just the driver's side open.
The new cover is also a brighter white than the old one, although that could just be age. I'm looking forward to installing snaps on the new one and seeing how my design works.
