Default Is this a '04 GTO clutch, and will it work in 4th gen Z28?

Searched and got some conflicting info, so thought I'd ask here. Hopefully someone can help.

These are the part numbers I can read off of it:

Pressure Plate:12562770
Friction Disc:12570280
Flywheel:12554130

I was told that this was pulled unused off of an LS6 crate engine (And I don't have any reason to doubt that).

The dealer tells me the PP number is for an '04 GTO assembly (for PP/disc/FW).
The dealer also said the Friction disc number is for for 98-02 Camaro/Corvette.
The dealer couldn't ID the Flywheel number, but it matches the old flywheel from this car so I assume that it is OK.

When I searched on LS1 tech, I saw one post mentioning the pressure plate number as a Z06 clutch (for the LS6) and one calling the friction disc as the upgrated disc for '00-02 f-body.

Do you think this clutch will work in a completely stock 99 Z28?
