It's always been designed/advertised as an emergency top. A new top from VM is same as CMC - header, w bars and tensioners. They do offer a Haartz fabric top (vs CMC vinyl top).
Heres's FaceBook link to top pictures.
Rafael in MX makes a folding scissors top that would most likely fit the CMC. Think the current Speedster that DrClock is building has one. You'd need to remake side curtains most likely. He probably has a link to Rafael's business.
