See lots of generic New buckets now days, but most are $500!! You have one now, and just need bottom rebuilt? I've done that to a Bobcat bucket once for my bigger tractor. Had to make the brackets for mounting too. We have a local welding shop making buckets and attachments for bobcats and does good job. Maybe some place like that around you that might build one? Seems on used ones the $$$ signs appear in their eyes when time to sell and think they are Gold.
