GM Heritage has the task of collating and preserving the available historical information [and providing it to you
free], documentation of production from a subsidiary division isn't their primary task - the fact that they have no detailed parts info for the war years does not mean "no acknowledgement of WWII every happening", it means they don't have the info you're looking for .... plenty of reasons for that, including something that's been mentioned here in the past involving a major fire at a facility that had a lot of the stored records, maybe you should try
Canadian GM [see under miscellaneous, vintage vehicle] .... I'd bet your inquiries to the Harrison company [successors] will find even less info about what that division produced at
any time, let alone the war period
