Still ...that’s good to know. Thanks!I thought the same thing when I got mine. The mounting flanges will bend outwards toward the sides of the bucket quite easily when you snug it down and remain in that position. You'll only have a bit of a struggle mounting it the first time...BTDT
EDIT: If I recall correctly, I cut a 2x4 to fit inside the width of the bucket in order to brace the sidewalls of the bucket when installing the piranha bar. That kept the sidewalls of the bucket from deforming which caused the mounting flanges of the tooth bar to bend out flush to the bucket.
Edit/Edit: Never mind, I just saw that you already installed yours.
