Does anyone know the OE part numbers for SS brake pads (non-brembo) front and rear?

I ask because GMPP makes some nice performance pads for the Cobalt SS, but they are not marketed for the HHR. I know the aftermarket companies list the applications as the same pad. Wondering if GM does as well? or do they maybe use a slightly different compound since the HHR is heavier?

 

It's easier for the Parts Dept to look these up if you provide the last 8 of the VIN.
