Default LS7 LUK OEM unsprung Clutch disk? Help ID

I Purchased a T-56 to put in my LQ4/9 from a guy on here and it came with a brand new LS-7 Clutch and used Fidanza aluminum Flywheel.
I am now ready to install but have noticed that the Clutch Disk is Unsprung!?
I have done a lot of research and can not figure out where this disk is from. I called the maker of the clutch LUK (maker of some GM OEM clutches) and none of the numbers matched there files for a LS7. And he said it indeed should be a sprung disk, not solid. Everything bolts and lines up fine... Can anyone explain my phenomenon?

Did they make an OEM Clutch for an LS7 with a solid un-sprung disk?

CTS-Vs (2004--2005 LS6s) (2006-2007 LS2s) come with dual mass-flywheels (sprung) and Unsprung clutch discs. The LS7 clutch and flywheel will fit these cars with the right slave. You may have one of those unsprung CTS-V units.

The original part number on 2005 CTS-V was 12568368, but GM changes part numbers from time to time.
