Ed,
What is a good one. I have an extra 1974 sanded smooth with green paint on it. It was on the car I bought from Army Dude for the Turbo Carrera 930 trans and v8 set up.
It is in Inglewood; CA and you can have it if it fits the bill for you. I do not think that I have ever seen a screwed-up top. They seem almost indestructible. No shipping you need to pick it up.
Regards,
Bob B
