Per the TSB the flywheel is a part number 12581141 and bolts 677665. The dealer ordered flywheel 12582861 and bolts 12569363. Can anyone confirm these are the latest and greatest? I don't want to have it replaced if it isn't the latest version.

The post card from the dealer also has a number 97226124.

ps - gmpartsdirect doesn't recognize the numbers off the TSB.

Here's my list of parts from my July replacement @ 109k (noise started at 107k):

Flywheel 24232434
Flywheel Bolts 97226124
Clutch Kit (pressure plate and clutch) 12582859
Slave Actuator (w/ release bearing) 15019756

All ordered from gmpartsdirect.....
