I watch videos on YouTube from Irontrap Garage. They are mainly into building traditional hot rods (1930s Fords) but also have been picking and reselling parts they find in various locations around the country. They recently had a big parts pick from an old barn that was full of NOS GM body panels - hoods, fenders, trunk lids, doors, quarter panels, etc. It included a lot of Pontiac parts, and they're starting to list them on eBay:
