Thanks a lot for this. So, I went to the hardware store with this information, showed them the pictures. First he said to hammer them out but I explained that there was no hole on the other side to push them out through. Then he wanted a closer picture of the rivets -- to see if they were hexagonal or what -- but I told them they were smooth. He said they didn't have anything for such rivets. He wasn't exactly enthusiastic about helping me.
So, is there any chance you could point me to what tool I need "drill them out". You don't mean I have to drill through the metal on the other side to push them out the hole, do you?
