The family business is calling my name, I'll be tied up for a while again...so my research will slow dramatically for now... but my the idea is to:
1. Try to find one or more of these warehouses and establish a contact. Maybe someone at one of these places could point into the direction of who to contact at GM
2. Try to find either someone in the group here (that maybe doesn't post much) or outside the group (like a dealer, parts guy, "redee guy",etc) that could help lead us to a contact at GM that is responsible for the Isuzu stuff acquired by GM.
