Barry:
I have a CMC "D" model. I needed a top too. I just bought one from CABRIOWORLD in Newark, NJ. I ordered it for a original "D". When I got it, I had to install the snaps (female ones - the males were already on my car). I have to say it fits beautifully! It is STAYFAST material, very thick, not cheap vinyl or psuedo-canvas. I can send you photos if you like. CABRIOWORLD has a website www.cabrioworld.com. Ask for Jeff, he and his dad run the company. Dad has a big $$$ Packard and has been in the business for over 50 years. The top was around $370, I believe. Well worth it. I ordered the header bow from VINTAGE, then used 3M Super Adhesive spray on glue.
