Buzz,
Sterling top had one that wold work--$25K (?) for R&D! Then close to $5K per top. That just about took care of doing a folding top. Sterling held and "kept" all engineering plans and even sketches of the top.
I will say it was totally impressive though, rear cowl was cut with at least three hinged areas to not only fold under the cowl, but to be able to work with a 3-point roll-bar!
Afterwards I developed one with hidden hinges on the rear cowl, a built in, self draining channel in the "cut". But, could not come up with a way to work with a roll-bar. When the top was down and folded up, nothing but a fine / finished edge where the opening on the cowl showed.
The rear of the top was "Fixed, no pins, clips, etc. showed with the top up or down. The rear of the top was already "fixed" in place under the cowl when the top was raised. Told CR's to send me a Cobra, (Like they did for the first DV) and I would design it for free and they were to have the tops built and sold. Easy to assemble for the home builder but "care" was essential on installation.
Installed: about 1 1/2 to 2 minutes to raise the cowl and completely secure the top in place!
With that CR's felt the cost was prohibitive for the average buyer. My plans sat in the engineering office for over 18 months, then just disappeared.........
Oh-well I still think it would have been a great option. The CR body was made for this top!
