Hey I know how that goes, I am the same way about my cars. The GM part number is 11516186. This is different than the factory installed bolts in that they are stainless steel(if you polish them they look chrome plated) instead of cad plated. I've had these on mine for over 10 years and they have taken on patina that looks like titanium. Kind of neat looking IMO. BTW since they have the correct hex flange heads on them no one ever notices . Thanks Eric Fisher
