It looks like just a shell of a Z06 roof covering the cage. I checked ACP's website but their world challege product listing only shows coupe roofs.

call ACP or ask LGM as they must know because they used them in WC

ACP has them...it includes the front a-pillars, wiper tray, roof, and rear section all in one. They may not have it listed, but they make it

It may be a factory gutted roof. I bought a frc recently and cut the fiberglass ribs out. Makes a lot of extra room for the bars.

After looking at my roof and where I plan on cutting out the support ribs, then comparing to ACP's picuture I think the car in the OP acutally has a modified stock roof panel. The car retains the factory A-pillars and just removed the trim, weather-stripping, and trimmed out the un-needed bits.

Here's the ACP roof for comparison... note the part of the b-pillar that folds in. The pic in the OP looks like my factory roof with everything removed in that area.
