Well I know he had to track down NOS stuff to be able to pull measurements from to build his tooling. I don't think GM stocks any actual parts for the purpose of "archiving" as it were. It odd nobody on any forum has experience working for GM Restoration Parts or its affiliates to shed more light on it. Besides being required to make enough parts to satisfy 5 years beyond typical warranty expirations for warehouses and dealers, I wonder too what (and where) becomes of the GM tooling.
