Found '76 Dart Sport - what are these holes?

Thanks guys! I'll go with side mounted turn signals or maybe antennas. The deal is, the car is for sale for $1500, no motor. 92 year old lady stored it for joe blow who has never come back for it. Just so happens joe blow's ex wife is the granddaughter, so she's sent a lawyers letter and now they're taking possession under the properties and storage act. I think she wants to spite him as well! She knows nothing else about it. She said, and I quote "It would be a good car if you put a 427 in it, that's what everyone is doing these days."
