The front bucket on my B21 is a little bent on the top and bottom. Looks like it has been overloaded at the lip on top and bottom bulging them out a little. Is it possible to straighten the bucket? Are there shops that do so?
Read your post a few times and trying to decipher what you're saying...Are saying the lip of the bucket, top and bottom are bent away from their normal position outwardly? Pic?
I straightened my B2910 bucket. Required some heavy metal bracing hydraulic jack and a torch. Doing a B21 bucket would probably take heavier equipment and more heating, because it is made of heavier material.
Try a heavy equipment place with a welding shop.
