I thought that too but the others do not appear to be touching the body. There are a few inches of clearance. I can not find where it may have come from because they do not appear to be doing anything. They just go through the frame rail. There are two pieces. The other must have a bolt that screws into the threads on this piece. As I mentioned, I do not have the other piece. The only thing I can think of is I had it in the shop because a bolt head was starting to come out of the floor and was making a lump in the flooring. They tightened it up. I wonder if they took it loose, lost that piece and used another.
