TheOgre says Amcor/Gorilla never provided security lug nuts. That they provided by another company by the same name. Obviously, he's wrong because this is the 4th car that has used the same Amcor/Gorilla key pattern. He said that what I have with the factory provided serial number decal didn't come from the GM authorized Amcor. I know TheOgre is a very smart man, but in this case I'll have to call him wrong.
