Identify this clutch

[Warrior1670]

Anyone help ID this clutch? Is it factory, centerforce, spec?

It was supposed to be replaced but I'm not sure. The only marking is the "d2" looking mark.

Also, the friction plate....how much material does a new disk have to the rivets? This one has maybe an 1/8" from the top surface to the rivets, maybe a little less (I didn't measure, just eyeball'd it).

Specs covers are all painted blue, typically centerforce is Orange so I'm not seeing it as one of theirs. No help on wear, I run metallic clutches that wear the flywheel and pressure plate rather than the disc.
