Back in 1985 a guy at my high school had a 1972 Nova vinyl top car with this top. It was the only one I had ever seen at that time and I have not seen one in person since. It was orange with black top and black interior. Beautiful car.

I've had three of those cars they are all west coast built cars. The tops were made by an English company and installed at the factory. He has the rarest color but there were good number made.
Skyroof Nova White (RPO WV1) 1,050
Skyroof Nova Black (RPO WV2) 3,075
Skyroof Nova Blue (RPO WV4) 164
Skyroof Nova Pewter (RPO WV5) 202
Skyroof Nova Covert (RPO WV7) 1,424
Skyroof Nova Tan (RPO WV9) 353
Skyroof Nova Green (RPO YH8) 554
Skyroof Nova (Total) 6,822

Wow - can’t believe the info that this group has access to! So, the 168 figure that my buddy quoted was approx the number of blue cars (164) with that option.

I knew a guy who had one ordered from the factory. Not many made for sure.

Alrighty, there are the numbers for 1972 Novas:

White 1,050
Black 3,075
Blue 164
Pewter 202
Covert 1,424
Tan 353

Option was produced in 1973 too, and I think production was around half at 3000+.
