Good advice kkm. If you don't have a grommet grinder ask them if they have one. Call USRSA and ask the best way to remove those grommets. I pull them put by hand and break them off where they are flared and pull them out from the inside the frame. When you put the grommets back in are you going to flare that grommet? If not make sure the grommet does not pull out when tensioning that string on either side.
When you're dead you don't know you're dead. It's the same way when you're stupid.
