Found '76 Dart Sport - what are these holes?

If all goes well, I'm going to see and probably buy this car on Thursday. I've struck a deal for less money. I don't know if it's worth the drive (it's a bit far) but it's an adventure in the name of hobby as well.

Apparently the cars been in storage for 14 years, as you see it. I figure if there's a lot of rust, it should be poking through that paint by now. I'll let you know what happens...
