I thought you were asking about the pic that looks like a cutting torch was used to enlarge the hole ?
I can’t imagine the line doing that,,,,maybe grinding,,,but not a torch .

Yes, it’s looks like it was hit with a cutting torch.
Agree I can’t imagine the factory would do this, but who knows… I’ve seen it on other Darts.
