Can someone tell me what these are?

What the others said. Let your chromer take care of it. The chromer here won't even touch **** that hasn't been welded by them. He's said it takes longer to fix it then it does to just weld it themselves.

As for RRR, take what he says with a grain of salt and maybe a shot of tequila. Like some liquor he's an acquired taste. But he will get the job done.
