Quindao, I honestly don't know. The link JBauer posted still seems to work:

... but I think it would be cool if your friend made at least the molds for the hard parts. I'm afraid that this is an artifact that has a potential client base that is getting smaller with each passing year, and once it is gone, it likely never will be re-created. I honestly wonder if I got the very last one - the seller wanted to be sure of the year of my car before shipping.
JB, don't know yet. Will order some hinges and a latch tonight, so I don't have to re-align panels every time I switch. I plan to test-fit next week. I can tell you it's a lot more solid than I had hoped for. And I see what you meant about the gap between the double layers of fiberglass. Will have to talk to my fiberglass guy about options for a moonroof, to see if it's even possible.
Will keep you updated!
