On top of the supercharger.. Someone have the GM part number?

Trying to order one off ebay and everyone with the part number I found say "does not fit vehicle"..

Im sure it "does fit vehicle" but I want to make sure before I waste my time..

 

Can you guys tell me if this is the correct one pls?
