from the P&P manual regarding core returns:
******************************************************************************************************************
Cores must be returned in the original container as the container serves as proof of
purchase from GM. Exceptions to the container rule are catalytic converters, fascias,
bumper covers, and select wheels. Proof-of-purchase peel-off labels must be affixed
directly to the fascias/covers and these cores should be returned without the GM
container. Certain wheels with peel-off labels can be returned in non-genuine GM
boxes with the peel-off label attached to the outside of the box.
