Which front rotors 2008 5.3

Hi!

I have a 2008 9-7X with the 5.3 V8.

I want to buy front rotors but I find 2 different part number with different dimensions listed. One is also listed for almost all GM version of this SUV after 2005 and the other is listed only for the 6.0 engine.



Which one does my truck uses?

Thanks!
