Russ from fibersteel.com has the coolest one I've ever seen, but like most of the stuff he intends to get to... it isn't ready, and may never be. I contacted him last fall concerning a racing tonneau, he took one to JPS to check fit, but never did modify it to work on a replica. I called once a week for three months, until he told me to forget it. I will probably try again, but only because I am VERY persistent.
