What you've been doing is re the photos, description, etc is great Marty, but it sure looks like a lot of work for the *hundreds* of different fasteners used on the Camaro, coupled with the multiple mfgs of each fastener...? I just can't imagine the time necessary to get all this documented the way you're going now. Then you have the issue of how to document the entire files so it's beneficial to the guys restoring? It almost begs for a color 'book' of many pages, which would be tremendously expensive. That's the biggest reason I had suggested a more simple spreadsheet format to couple with the existing AIM and other documentation available (like the AMK catalog? etc)...
PS. I took photos tonight of the two screws you wanted which retain the cowl vent panel, but my camera will not focus close enough to capture the detail you require (and is exhibited by your photos). I'll find a way to do this and then send them to you even if I have to borrow or buy another camera with a closeup lens capability.
