Kubota Quick Coupler Repair

I have a KX161 with a worn quick coupler. It appears that most of the wear is in the ears on the bucket. What would be the best way to repair this? I have thought about doing a build up on the bucket, but I have some concerns about how to re-shape it to fit the coupler on the machine.



Alternatively, can the bucket and coupler be repaired at a machine shop? Hopefully they won't need to be replaced.....



Thanks.
