k4hal,
I did that too and they are handy. Mine are bolted back further on the bucket on a large sheetmetal surface that is not as well supported as where yours is. Somewhere along the line, probably when picking up a large centered load, it put enough side force on those hooks to bend the sheetmetal they are mounted on. (~3/16 inch thick) I'd like to find some of those with a wider mounting surface.
