Does anyone know what the GM part number might be for the EGR gasket on a 06 LBZ? I am a machinist, so I planed on making my own blocker plate and was going to match the profile from a factory gasket. The dealership ordered one for me but the profile doesn't look the same. The part # on the one they ordered was "97303655". I think the parts guy ordered the gasket for the other end of the EGR valve. I wanted to verify the number when I went back to the dealership.

8 digit part#97372002 or 10 digit part#8973720021 Gasket EGR cooler in.

Thanks for the help. I'll order it on Monday.
