I found the top on club cobra a guy in pa. makes all sort of glass parts for various cars.
he made the top to fit a original 289 street car around 10 years ago and had the mold. he claims that he made only 1 other one for a guy with a f5.
the back part of the top fits the hurricane body great ( just alittle glass work) the front i had to cut and have to add a 3" piece of glass which I think relates to the windsheild angle being less then the originals
The top came with a back hatch inner and outer panel that I will bond together once I fit all the harware and blocking inside, I will need to make all the glass panels and come up with the gaskets and hatch stays
the top cost me $700 with crating plus my shipping cost to ny @ $165
Here are some pics of the top on a f5
